Painting Basics & Techniques - Part 1 of 2 with Kevin Tetz - Eastwood

great techniques gun handling techniques gun setup air hose handling sequencing a paint job and we're also going to be talking about a whole lot of other things like airline systems the importance of filtration the importance of air volume rather than air pressure so the other cool thing is that below this you're going to see icons pop up talking about some of the equipment and tools that i'm going to be holding up there all available from eastwood and some of them are on sale you can find all of this stuff at East was so I just want to let you know that in advance the other cool thing is that you can actually feel questions you can you can talk to us and at the end of this presentation we're going to answer a few of those questions that you guys have a switch is one of the beautiful things about what we're doing we are alive it's like it's like a news report we're live here and it's very cool to be a part of this if you don't know who the heck i am i'm kevin taste I I own and operate and produce the patron location series also do some TV shows i do the truck show on spike and I just want to say out loud I'm a really good painter now that might sound almost full of stuff like that but there's a reason that i can say that I'm a really good painter is because I've painted thousands of cars it's not because i have God's gift of painting you guys anybody can be a really good painter it's repetition it's conscious thinking it's muscle memory and that's what it is you gotta pay attention to the rules get your setup right and do it over and over and over and over and over and over and over again to practice practice practice practice practice and you guys if you're a beginner if you're a pro you get better it's muscle memory so when I say I'm a really good painters because I've done it a lot so all you gotta do to get your skills up is just practice so let's get started we're going to talk over here a little bit about air compressors now the air compressor is the heart of your shop I'll say it again air compressor is the harder shop everything else depends one hundred percent on the quality and the volume of air that you're putting out here's some requirements i hope you've got a notepad if you don't these presentations are available for download later you can view them later on and you can take some notes because there's a lot of important thing there's a minimum that you need to paint a whole cart you need at least a five horsepower compressor a two-stage air compressor preferably with a cast iron pump a minimum of a 60-gallon tank and you're talking about spending some money you have to have the proper amount of air volume air pressure doesn't matter in painting any more air pressure is for your tires it's a totally different set of equipment and set of systems air volume CFM is key and when you read the guns what they are required to have it CFM it's not pressured about 12 to 13 cm some of the lower drawing some of these two guns are drawing less but he hears the difference you can have you see the difference in the inside diameter of this and this pipe ok you can have the same air pressure or the same volume air pressure in both of these pipes and the volume that's coming out the end of this one is much greater than the volume that's coming out the end of this one so the volume is what atomizes and breaks up the paint so you can breathe through a straw or you can breathe through a culvert pipe breathing through a culvert pipe is easier and it's easier to paint so think of that analogy when you're setting up your system so now that you've got your air compressor I wanted to show you something else this is what I'm plumbing my main paint shop with its it's a system that i got from eastwood is three-quarter inch inside diameter airline and the fittings are really cool there are push lock style fitting that has an o-ring system and a feral that compresses on top and it makes it makes short work and make sure your airline routing very very easy and the system that I've got has a hundred feet of the Blue Hose it's got several fittings several junction several unions and the cool thing is that it's flexible so you can bypass a lot of the need for four look what you can do with it and it's lightweight aluminum with with a nylon membrane and it's really versatile so i highly recommend that that again it also is available these wood let's talk about filtration you've got to have clean air got to have lots of air but you've got to have clean air so this is the little ball filter that you you can buy and these you can screw onto the end of the paint gun and this will filter somewhat of the debris is i don't recommend just this this helps if you've got a problem sometimes this can solve it on the fly don't depend on this - to save your paint job this is called a desiccant snake it's filled with desiccant now we're going to explain this again in just a second so hang on this goes in line to your air system and it's got a silica inside it that will absorb moisture it doesn't compress it doesn't interfere with your CFM delivery so this is a nice fix if you're doing a limited amount of painting and I it this relatively inexpensive when they wear out you replace them then you get into your different regulators and filters this is just a regulator with a gauge on it with no filter whatsoever this has got a filter you can mount a gauge and mounted in line with the regulator you've got to have a regulator to get your air pressure where you want it this is the mack daddy of all of it this is a three states a multi-stage desiccant system now desiccant is this stuff these aren't silicon under silica what's silica beads that absorb moisture and it works exceedingly well these packets or what you get with modern electronics when you buy a TV when you buy a computer they're all packed everybody's seen these they come flying out of the box you throw in the trash they are the same thing is in this and they'll be in your canister in line in your air supply and they will filter out the moisture this is multi stage these two are designed to catch particular this is designed to catch moisture and you again you've got to have clean air you got to have lots of air but you've got to have cleaner so think about systems like this now i want to make something very very clear if you buy this stuff and you don't install it correctly you are wasting your money so if you're not going to install it correctly don't don't even bother you just you know throw caution to the wind here's what i'm talking about what happens when air compresses it's a piston just like an engineered super heats that air when it comes off the manifold it's hot so if you put your expensive relatively desiccant system right on the manifold or a couple of feet off the manifold that air is still packed with moisture and it goes right over top of the filters it doesn't get separated so what you have to do is sit this at least 20 feet preferably 50 feet away from that hot manifold of your air compressor and you might be saved yourself i'm in a one big garage i want to plummet i'm in a small shop I don't have 50 feet i've only got 30 foot walls here's something now don't plum with PVC i want to say that out loud right off the bat this is PVC and i made this piece just for demonstration purposes so what you can do to cheat distance is go up and down and up and down now this is 10 inches here this is 20 feet of three-quarter-inch ID piping so if I was to double this I've got 40 feet of of drying air of giving my air the the capacity to separate from the moisture with this and it also gives you the opportunity to mount a ball valve bridge drain valve down here and get the water out and be able to evacuate so it doesn't fill up with water so thank your way through this stuff you can cheat distance with something like this plump it up and down you don't have to have a 50-foot wall so keep that in mind when you're planning your airline system let's get to the good stuff let's start talking about spray guns before we go into demos on the guns one of the questions that keeps coming up and and we've talked about this with the east with guys before we planned this this presentation is gun settings air pressure settings yes you have to have up you have to have the pressure set right and the gun recommends 10 pounds of the air cap it almost makes me angry that the gun manufacturers say 10 pounds of the air cap because for you and I there's no way to verify that it's 10 pounds at the cap is not a gauge on the gun and there's not a gauge of fits on the inlet to gauge the air pressure at the cap what you have to do is factor in the air inlet pressure right here now ten pounds at the cap a rule of thumb is that is going to give you between 30 and 34 pounds at the inlet so when they say ten pounds at the air cap just don't even worry about that worried about the inlet air pressure which is the pressure coming in to the base of your gun now here's the thing to people say well I set my air pressure but when I pulled the trigger is it goes all screwy well when you set your air pressure make sure your triggers fully depressed and whether you got a wall regulator or a regulator on your gun pull your trigger let air going through it is pressure is set with the device completely open so keep that in mind as well now what am i doing with these things taped to my paint guns extended stupid but there's a method to the madness here these are what I call dry training guides and they're perfect for for learning gun handling techniques like I said right off the head it's muscle memory its repetition and these give you the opportunity to to understand what it feels like to be in the awkward strange positions without even having a single bit of fluid go through your paint gun let me show you what I'm talking about now the bristles the bristles of this brush represent where I want my spray gun on the surface and this right here this is a Ferrari just in case you were wondering now what I'm doing is I'm practicing my technique by keeping the bristles just barely touching the surface and I can practice my overlap and I can practice moving i can do a rehearsal on the panel to see if I'm gonna run over it but the most important thing is that up here in my wrist I'm getting a feel for how it feels when i'm in in the right position in a nice comfort zone using correct technique my wrist is well i'm going to overhear my wrist is broken it's not like that i'm not sweeping I'm going in a linear format and my wrist break so that the brush on the end of the spray gun is a beautiful training tool and it's surprising how effective it is for you to it really sets the light bulb off to know exactly where your surfaces in relationship to your spray gun takes a lot of the pressure off another great idea is this guy right here the reason is sometimes it's easy to get lazy with our spray technique now when i'm lazy my spray pattern is like this when I'm just kind of pointing at the panel with the gun and my pattern obviously is going to get really heavy down at the bottom and really light at the top and it's going to tiger stripe it's going to be inconsistent it's not going to be what I want and this gives me the ability to test myself and keep my gun perpendicular to the surface 90 degrees spray pattern parallel to the surface so again it's a dry training guide that shows me if I'm off-kilter one way or the other and lets me memorize this natural position that i'm going to have the best painting results so keep that in mind when you're spraying paint rehearse Ron covell talks about being excuse me when he's welding he does rehearsal to get is his comfort zone to get his is muscle memory built up before he starts painting and before he starts welding and painting is absolutely no different you want to be in a comfort zone what I'm talking about the comfort zone is I don't want to be out here going crazy painting out here and and I don't want to go over here like this I want to have his own to where I'm in control painting is all about control your controlling your air your gun your fluid and your surface so if I'm out here if I'm out of control I take a step get in the comfort zone so keep that in mind as well now i'm following an outline because we want to make sure you have time for your questions so I'm gonna be looking at this from time to time ok so we've talked about spray gun technique let's talk about air hose technique and why is that important I'll show you another thing to consider as well as your CFM on your air compressor is CFM in your air hose I don't recommend anything longer than a 25-foot air hose because you you you experience pressure drop over distance the other thing that's very very important is to keep a 38 inside diameter airline and three eighths ID fittings which these are not these are five sixteenths they're not three eighths the difference between this and the professional spray gun setup that I've got in my booth is night and day I have seen an itch difference in this in the length of the spray pattern by going to three eighths ID fittings very very important for a good effect of a good effect of spray delivery so what I'm talking about with the air hose this is nobody's going to do this really unless you forget when I'm over here guess what my air hose is do it it's touching the panel and at the very least i'm not going to bunch of trash into what I'm about to paint or worst case scenario i'm dragging my air hose into wet paint not good so this is what i recommend take your air hose clip it over the shoulder that's not good enough because look what happens it can call off the shoulder guide it with your other hand and you're using kind of a push poll you're controlling your environment there goes my guys and as I'm you see what I'm doing as i'm increasing my distance away from my body I'm feeding the air host when I come back I'm pulling it back take a little while to get that memorized but it's very important to do so just think your way through this stuff in a rocket science but it takes some thought and it takes some repetition we're going to put this over here let's talk about gun setup now that we know what we're gonna paint we know what we're gonna paint with and by the way this is this is the the concourse gone from us what is a very nice piece of gear of the evolution guns or what you just saw they're very cost effective and they're nice guns i use these guns on jaded when I shot it and I'm very happy with the results sometimes even the best spray guns can get a goofy pattern just due to maintenance and stuff collecting into the air horns and things like that so right here this is a representation this is an elliptical pattern this is what you want to see this is like a football shape and that's what you want to see out of your spray gun now if it's like this if it's heavy on each side and light in the middle that means you're blowing it out with air pressure your cranked up too high some of the spray guns only want 20 pounds at the inlet 20 to 30 pounds is typical so you have the opportunity to test on some sort of a take-off part or a piece of cardboard like this set your spray gun before you paint your car just like you're welding well on a piece of scrap before you you put your quarter panel in so this one right here this means it's heavy on one side having on the other side but it's it's cyclical it's it's it's a curved like that typically what that means is that one of the air horns is blocked these are the air horns on the spray gun tip now one of those might be crusted up and blocked so you know it's a simple matter of cleaning it but that's what that will tell you so see now check this out - this is the digital air pressure gauge this thing's Nate if you got to have a pressure gauge on the end of your gun this allows you to to adjust on the fly and it's very accurate so we're going to stick with a fairly low pressure we're about 20 for the inlet so let's do it let's give it a shot so what do we got there we have the perfect elliptical pattern we've got the football right there buddy the reason we have that is because we're allowing the spray gun to do what is designed to do I've got the fan fully open I've got the fluid delivery fully open that's not to say you have to shoot like that all the time but that's the optimal setup for me now we've got an air volume adjustment down at the bottom of the gun body which is nice to have if you want to adjust on the fly here if you're going into some some tight recesses it's nice to have that and here's your fluid delivery here's your fan that's a fan that's blue delivery so watch what happens when I tweaked and i want to improvise is my pattern starts going away and what's going to have to you right there if it's going to run all over the place you know we're not doing a collages or or art work we're painting cars and we want a nice overlap so you can if you've got a cylinder to get inside it's really uncommon for me to recommend that you choked your your fan pattern down and it's very uncommon for me to recommend that you choked your fluid delivery down here's why see what I'm doing there it's misty what's going to happen is I'm going to get a rough surface i want a flat surface i want the pain to flow out and self level so I want to make sure that i'm letting the expensive spray gun do it is designed to do now I know some of you guys are saying this knucklehead is showing me how to spray paint that he doesn't have any safety equipment on here I want to show you something this is acrylic craft paint I'm not being dangerous here there's no overspray in the air because this is a high quality HVLP gun it's not given me over spray and this is water-based craft paint now when we do make some overspray of course i'm going to have a mask on so well I want to make sure that you understand that i'm doing this for demonstration purposes only and that it's a safe way to demonstrate these techniques to you guys so always always please keep safety in the forefront of your mind these chemicals that were using when you comes time to paint are dangerous and their hazardous to handle as well as to ingest into our body so please be careful and this is actually a good tip for you guys as well get some craft paint it's not that expensive it's certainly not as expensive as automotive paint and it allows you to play around with your equipment and set things up and and get a feel for what you're doing so let's talk about let's talk about overlap what am I talking about with overlapping that's a universal spray technique that you want a 50-percent overlap what am I talking about with that I've made a pass there a 50-percent overlap means that i'm moving halfway down fifty percent from that pass and backtracking so this way fifty percent down overlap fifty percent down overlap fifty percent down overlap now i'm stopping and starting and you can see what's happening as well you don't want to do that because you get a heavy build up on the edges I stopped and started so I could talk to you guys and show you but you don't stop and start with your fluid delivery when you're painting to ease the trigger off because you can keep the air going the same time you're delivering you delivering paint so here's your technique it's not perfect it's the first coat is black on the light substrate so that's what i'm talking about with overlap fifty percent overlap you want you want your vehicle to appear as though it's been dipped you don't want random dry spots and a 50-percent overlap or some kind of an overlap helps you build that code from one point to another point so very very important to perfect your overlap and pay attention to what you're doing and the gun handling techniques will allow you to be in a nice comfortable position in your comfort zone while you're doing that speaking of comfort your hand this is your guy this is what's what your eyes are telling to move through your brain so here is your standard prone position for a spray gun if I want to pay up high like that on a van or something like that if I keep the same hand position it's goofy I'm going to get a heavy pattern on one side so here's something that I've learned over the years you can change your hand position see how my wrist is broken there you can change your hand position to to suit what you're trying to spray so I've just suggested my hand position and as I'm coming down I'm unlocking my wrist and now i'm in the prone position the same thing goes for getting down a little bit lower now typically I get down on my knees I'm old I'm old as dirt my knees hurt I don't want to get down on my knees in a concrete floor anymore that was in my twenties I'm not that anymore so what I've also learned how to do is adjust my spray gun and when I cup it like this but my palm over top of the controls now guess what I can do I'm down here and I've got a parallel pattern just like that perfect so if i don't want to get down like this on my knees and getting my comfort zone I can make a quick adjustment of my hand and go from the prone position to this position here and have perfect technique so keep that in mind when you're moving around on a larger vehicle so we talked about overlap we've talked about getting your gun set up properly we've talked about about proper techniques handling your air hose here's something is very important I want to talk to you guys about sequencing a paint job here's the analogy you want your car to appear as though it's been tipped as though you've grabbed the covers and pull them up from your feet all the way up to your neck in one continuous coat sorry if that's goofy that's just what it made me think of but you have to sequence your paint job on a complete overall and this comes up an awful lot in in the website forms that i that i visit the eastwood online restoration forum where do you stop where do you start let's talk about how to sequence a paint job but can do we decide to go over on that side are you okay there okay now keep in mind this is my RC mustang it's clear and i'm going to be drawn all over it so obviously in this frame with you can't move the car around but this this is what I'm talking about now I always start on the roof of the vehicle in an overall there's a couple of different reasons for that typically your air flow is coming from the top down and creating an envelope around the vehicle even in a semi drown or a crop a cross craft paint booth the top surfaces are going to get hit first if I shoot the sides and then come up to do the top last I've got wet paint here that i have the potential of messing up so when I start here and then work my way around the vehicle and come up here by the time I get back to the second coat on that top well it's probably drying up for me to stood to start again and I don't risk messing up my sides anymore so the sequence that I've learned over the years i call now this is in the Patriot asian video series i go into great detail in the videos to demonstrate this but i'm going to go ahead and do it right here basically what I do is I start I like the driver's side I want to start on the driver's side and I do what's called a push-pull method I'm going to explain push-pull very clearly on a Ferrari right here so what I do is step number one I paint from the edge from the drip rail to the middle now a lot of guys start from the middle and work your way down I don't like it I don't like doing that because you get a dry spray in the middle and its tax the paint up so push we push to the middle now we jump over to the other side and we start from the middle where it's still wet we grab that wet edge and drag it across that step number two now I'm leapfrogging I'm leapfrog and that's what that means you're going from side to side to side to side to side and you're creating a wet surface that grows through the car so step one step two I'm leapfrogging over back to the driver's side quarter panel and I paint my quarter typically i like to start from the bottom and work my way up because that allows me to push across the side so i'll come up over here right to the sail panel and then i'll eat proc over to the other quarter panel and i paid from the bottom up not riding on my door gap and i'll explain that in just a little bit and i paid my other quarter panel and because I've got a wedge here that i was just at now I can paint my way across that rear deck because I can reach it easily from the back bumper position now I can catch up with my wedge now that I've got this I pick up the tail panel and I paint the tail panel now I'm leapfrogging back again over to hear my edge here is still wet enough to where I pick up the door and I sprained my way up the door getting past my panel gap there's a really good reason for that past my panel gap and it makes sense just to stop and start at the panel gap because it naturally breaks up the car however due to surface tension you're going to have a heavy build up on that gap if you're doing a metallic or a candy it can really really bite you in the buns and make sure that you see that transition you don't want that so I pet it past my panel gaps and I leapfrog over to the other side hope you're getting the picture and we paint our way up this door again again pastor panel gap so now what we've got is what's called the doghouse it's the front end of the car this edge is still wet because i was over there less than a minute ago but it's dry enough now to pick up the wedge and I worked my way forward so I pick up the fender work my way around the wheel and I push my way across the the same way that I did on the roof and this is the push-pull method you push to the middle and then you pick up the middle on the other side you walk around pick it up and you pull it from the wedge and you keep it a continuous overlap all the way down until you've come all the way across the doghouse and this edge here is still wet enough that you can you can have this continuous coating and if you got a lower fascia grill pick up your dry edges there and you've got one continuous code on that paint job that looks like it has no dry spots there's no transitions and you know where to go and typically by the time you work your way around a car it takes 30 to 40 minutes to do a single code on a car well there's your Flash time so - then you can go into the spray booth make sure got your cup again and start over start with your second coat or your third coat so that's how I like to sequence a paint job and here's another demonstration go back over this hot rod here and we do have a little bit of time ok so I'm coming over here if I stop right here here's what that gap looks like that's looking down at that door now my paint is going to bubble up here it's going to be get really happy right there you've seen this on cars on original equipment cars so if you stop and start right here you're just accentuating that and you're building up crazy layers of paint right here right on that gap you don't want to do that you want to the first coat maybe its prey up till here when you come back around for your second code stretch it over to here on your third coat back it off over here make sure you're getting three full coats change the position of that that will really help you especially with translucent colors or candies that is a that's a great technique if you're working a candy walk beside that's a that's an advanced technique but this right here will keep you from having runs in the gaps nobody likes the runs no different in painting yeah yeah
