How to Wet Sand Orange Peel in Car Paint: Porsche 911

hey guys real quick before the video starts i want to reach out and remind you that we have the all-new ammo pivot bottle coming out pretty soon but i do need your help if you can go to the link down below in the description and sign up for the kickstarter campaign we only have a few days left uh to help us sort of fund the project and be able to get these triggers to market so if you haven't done already please go and check it out as always thank you so much for your support and enjoy the episode what's up guys on today's episode we're working on this beautiful 1980 porsche 911 as you can see there's a ton of orange peel in the paint so today we're going to be talking about how that happens and how to remove it with my special guest jason rose from rupez usa [Music] okay first off thank you for being here i know you flew in we have a couple of cars to do and this is one of them a really important car this is covered completely in orange peel so first things first explain what orange peel is and then how it occurs on a car that's been repainted that seems to look pretty good when it comes out of the booth and then sometime later it it doesn't look as good it looks like you can surf on these waves as they say right so there's bumps in the paint that's what that orange peel is the thing that happens with a repainted car like this one yeah the paint comes out of the gun wet it hits the surface and then at some point it dries so solvent is the carrier for the solids the solids is the paint and the solvent carries the paint to the surface what happens is the solvent evaporates out and the paint settles a bit now during that process of it settling down the paint could get texturized because it's literally shrinking down okay so now that we've identified that it's uh orange peel how do we take it out well we literally are going to be removing some paint so the the peaks and the valleys that exist in the texture we're going to be knocking off the peaks so that's how you repair this so it involves some sanding and then it involves some machine polishing but we're first going to measure the paint thickness to understand our baseline thickness that we're dealing with and then after that we're going to do a film disc sanding procedure that will chop off the peaks of this texture followed by a foam disk sanding procedure and then one or two steps of machine polishing and then it should look flat as glass step one is to wash the vehicle if necessary and in our case since it's stored in a museum it doesn't really need it on the other hand we do need to remove or break up any wax that may be on the surface that might cause the sanding disk to ride over the paint instead of on top of it to do this jason and i are using a 50 50 mixture of isopropyl alcohol to remove any basic layer of protection next we removed the badges the front intake we taped up the trim the door handles and all the tight spots then we covered up the wheels to avoid them getting covered in sanding residue over the next two days [Music] the first step is to dry sand with a 1 500 grit film disc to level the texture now this step can be done wet or dry based on the type of sandpaper you're using now in our case step number one is dry because the disc we're using is designed to be only used for dry sanding so make sure you pay attention to the particular disc you're using okay before we get too far down the path let's keep in mind there are two places where people tend to get into trouble with these film discs number one the discs are designed to remove layers of paint if we see orange peel that say in our brand new car and you want to remove it with a film disc you can do it but let's just say in this scenario that you do remove it it looks absolutely perfect you're thrilled you've actually thinned out the clear coat jeopardizing the integrity of your paint's protection so in theory again if let's say six months later you have a scratch in your car and you want to remove it you don't have any room to play anymore you've removed all or most of the clear coats so keep that in mind red flag number two is people tend to choose a heavier grit than is actually needed to remove the texture this is where a test spot is absolutely critical you must use the least aggressive step when texture leveling so sort of think to yourself what's the finest grip paper i can use to remove the texture as opposed to just hitting it with a bazooka and leveling it you're going to remove too much clear coat okay lastly if you're watching this video and you want to sand your car the truth is there's way more reasons to not sand your car than there are to actually do it the reason we're doing it here is because this particular car was poorly repainted years ago and there's a ton of paint on the car as you can see with our paint depth gauge most average factory paint jobs can range anywhere from three to six mil and this one is reading in the low 20s on the ocometer so we have plenty of paint to sand and it makes it a perfect candidate for the job okay with all the disclaimers aside it's now time to get started and because we have multiple people working we're able to simultaneously do three inch sanding for the edge work and six inch sanding for flat wide open spaces to set up the machines we're using foam interface pads under the film discs to minimize excessive edge cutting and to minimize pigtail marks during the leveling process your goal here is to see the glossy sort of textured or orange peely paint converted to a flat appearance with white dust if you're dry sanding or white liquid if you're wet sanding this white powder or liquid is the clear coat material coming off the surface as you're sanding after a few passes wipe off the residue and then inspect to paint to make sure you remove the texture obviously if you haven't then repeat the same step until you're satisfied with the amount of leveling likewise i know a lot of you guys are going to be asking but it's a huge challenge for me to tell you how many discs you're going to use on a particular project because paint hardness obviously varies from car to car so just pay attention to when the disc slows down its rate of sanding the way that you're going to know that is it's cutting less which creates less sanding residue so then when you see that it's now time to switch to a fresh pack [Music] another thing to keep in mind is what we call the sanding rule of thumb this is where you leave a thumbnail size space unsanded around all the edges for safety before you start a project you have to ask yourself does this have to be perfect or just much better is it a daily driver or is it flat bedded to car shows here's why properly sanding edge work takes hours even days longer to complete a project to avoid burn through or just the tedious nature of working in tight spots alone in this case it's daily driven by the owner of the audrey and museum so we left a thumbnail sized space around the edges to avoid days of unnecessary work once we finish with 1500 then we use 2000 grit foam back discs to refine the previous step of the 1500 where the 1 500 disc is focused on sanding the very top parts of the orange peel the foam back discs the 2000 discs are designed to sand in between the peaks and valleys sort of contouring to the paint and leaving a much more refined surface which prepares the paint for the next step of compounding and polishing now unlike the film discs that can be used dry or they can be used wet the foam back discs of any brand they're specifically designed to be used wet or what we call damp in this case we use the spray bottle filled with water and we give a light mist to the disc and to the paint which is why we refer to it as damp and not necessarily wet just like before you should also see some white liquid from the previous step because you're removing material again just at a slower rate [Music] once you're done with the section you can really see the difference between the 1500 which is in the middle of the hood here that doesn't show any of the above lights and then the 2000 foam disc on the driver's side of the hood that is beginning to show a little bit of the outline of the lights as we get closer to a flat and reflective paint surface [Music] okay now here's where it gets fun once the entire paint has been leveled with 1 500 and then refined with 2000 grit it's now time to remove the remaining haze with the rupes 21 blue coarse compound and the blue d a wool pad on speed 4. now the benefit of the 2000 grit foam disc in this entire process is that you can actually use a dual action polisher to remove the installed haze where in years past you'd actually have to use a rotary polisher compound wool pad etc to get the sanding marks out of the finish [Music] after each section be sure to blow out the pad and then apply two small dots for the next area likewise use a three inch pad and machine in the tight spots as needed next for the second step polish we use the white pad and uno pure ultra finishing polish it's called pure because it doesn't leave any solids or materials behind to prepare the paint for the protection phase after the last step refinement was done we protected the freshly restored surface with reflex pro which made the paint absolutely pop before replacing the badge grill wipers removing the tape cleaning the windows and adding mud moisturizer to the tires and the rubber trim one quick way to measure the clarity of the paint is to look at words on a wall on the other side of the room let's say while looking into the paint in this case we looked at the ammo shield and read the words on it and they were nearly perfect and the distinctness of the image was remarkable after the job well guys after two days the paint looks absolutely phenomenal the difference between before and after is huge hopefully the camera is picking it up you can really see it in the hexagrid lights and all the lights around here uh stunning so the recap here is we did 1500 2000 and then we used the rupes new da system the compound and polish yes absolutely insane i'm going to be doing a couple of different videos on that product line as well specifically on the one behind us right there a little bit of a sneak preview uh the glickenhaus boot but really uh the only thing that's left to do is to take this back to the aldrine museum a huge thank you to them by the way for letting us work on this amazing car and there's gonna be a lot more coming up from them as well so make sure you check out their website so only left to do like i said let's get in the car and drive it we need to make sure that the paint is okay after our little joyride the team from the audrey museum arrived to pick up the freshly sanded 911 for the owner nick now at the same time the remack arrived at the studio for some detailing and of course it started to rain so getting the 911 in the trailer without getting it wet would be the next challenge so we moved the trailer as close to the door as we could and jason dressed like he's in the witness protection program along with my neighbor steve's dad and i held pieces of plastic to shield the porsche from the rain as we pushed it in but of course there was one issue oh jason go ahead dripping [Music] got it i give you one job [Music] this is your walk of shame look at the drippies go ahead give the man one job give the short guy the job you see we had it perfect and it was all funneling in with the 911 all packed up we arrived in rhode island to present the restoration to nick wow his tails never look like this it's amazing everything looks like better than new to see my full interview
