How To Repair Chips & Scratches On Your Bike | Professional Frame Painter's Repair Guide

[Music] there is nothing more devastating than scratching or chipping the paint on your bike when it happens it can literally ruin your week you can be ever so careful with your bike treat it like a baby but that's all it takes is a gust of wind and there you have lovely chip on your bike but when this does happen what can we do to fix it well in this video we're going to show you how the professionals fix it and how you can fix it at home hi ally hello nice to see you nice to be back in the workshop yeah yeah a little bit dirtier than last time lots of bikes here we're here this time to learn about chips and scratches okay um i know nothing about how to fix chips and scratches so what can you tell us well hopefully i can show you how it's done we've got a couple of bikes here today i can show you examples on this customer was unfortunate and dropped her bike that's quite deep it is deep this is down to the carbon it's not through the carbon so we don't have to do any uh work on the carbon but we're going to put a tiny piece of filler in here um prep this area and then go from there to start with obviously we want to keep the area that we prepare you keep it to a minimum but you do have to feather out yeah i'm just i'm surprised actually how far out you have to come with when you know it's just such a small no this is this is where some people misunderstand when you quote for a chip it's probably it's not a matter of dribbling in a little bit of paint you can guys can do that at home and you can get really good results you know hopefully we can show you that later um but when you do it professionally obviously the customer expects not to be able to know it was there and so there's a lot of stages so first stage where the chip is i've already checked there's no loose paint so basically what i'm going to do is i'm just going to scratch inside this area so that the filler that we use can adhere to the chip so there you go now we're ready for some filler nearly all fillers like this are two part and what the manufacturers will say is take a golf ball size of filler and a pea size of hardener we're not going to use that much so you kind of have to just guess really mix it thoroughly and then take the littlest bit you can on the spatula because you've got to sand this off and it can become quite a pain and then literally just spread it in the chip [Music] so initially i'm going to use a 320 grit piece of sandpaper it's um dry it's for dry sanding so you wouldn't wet this and this will just take the excess filler off just do it really light because again you want to localize the repair as much as possible so this is just to get any lumps off that are proud okay so basically now we'll get it in the spray booth get it masked up i'll show you the weird masking materials that we use for this to give us a nice soft edge and then we can get the priming done perfect [Music] [Music] so it's really important that you mask the whole frame up because you're focusing on this area and i have had it before a long time ago before you know you learn as you go along you think yourself i'm only painting here i don't need to worry about anything else but we're focusing on this you'll get this area perfect but if you haven't masked off somewhere else you can end up with a tiny bit of overspray falling down here or over here and you won't see it because it's not been your focus of attention so we absolutely mask the whole frame off now whenever we do any repairs okay so you've masked the bike up mix the primer what we're on to now right so we're going to put several coats of primer over the damaged area um it's in the airbrush ready to go these masks aren't perfect masks for the paint materials we're using but the volumes we're using are so low this is going to be more than do the job so if we mask up how many coats are we going to give this at least four coats okay so that we've got a bit of a build of primer there that we can then flat back and then that div it that low feeling that you felt will be gone and then the drying time in between the coats five minutes between coats nice let's go so ali's done about five coats of primer now what's the next step so we've it's dried now so we'll take it over to the flattened bench we get it unmasked and we'll smooth that primer back ready for color [Music] so basically we've gone through the different grades of paper to get it smooth and flat 2000 grit paper what i'm going to do is i'm going to sand past where i'm going to paint the new lacquer and then this will give us an area where we can blend the old lacquer to the new so we can basically polish them both together [Music] that is that's smoother than a baby's bum that's lovely in it yeah it's lovely so we're ready for color but we are quite close to this red detail here so i'm going to get bex to measure it and we'll um on the plotter we'll cut a couple of stencils and i think i will cover these three up so now that's all done guess when it's time to get painted it is time to put some color on [Music] so [Music] i think that looks great already how many coats to paint was that a lot of paint actually it's very see through the red so it took quite a lot of building up i was a little bit worried to begin with but i think we're there now yeah that's kind of quite well probably eight or nine coats really yeah yeah so we just gotta peel off the stencils um and then we're ready for some lacquer that's would that be the final stage of the paint side of it yeah and then it's just some flattening and polishing after that [Music] [Music] so [Music] so the next part of the process is just waiting um waiting for the paint to dry here so we did put some rocket in that lacquer so it should go off fairly quickly hopefully we can flatten polish that so we'll flat the whole area and these ends are mainly so that we can blend blend into the old paint probably about 45 minutes with the um rocket that we found is there a risk of this top tube looking better there's not a risk it's inevitable yeah it will yeah yeah um because obviously factory paint there it's done to a budget you know they haven't got time to do a flat and polishing um kind of process on their paint you know the the retail cost would jump up massively um so yeah the unfortunate thing is the top tube is going to look much nicer than the rest of the bike but not to a point where it's really noticeable someone that knows paint will look at that and think oh that's lovely and they might then draw their attention to another part of the bike that's just normal [Music] well this make it feel like a baby's bun it will make you feel like a baby's bum not that i've felt many babies buns lately just want [Music] final stage yeah polishing [Music] [Music] do i i think it looks better than than it was probably before yeah yeah it's probably a little bit smoother the lacquer in a little bit smoother than standard and we've managed to blend in where the old meets at both ends and we've managed to blend the color from the damage out it looks absolutely incredible to me you'd you'd never know that that's well no i wouldn't but you are a bit of a perfectionist yeah i think is that up to your standards just about there i think yeah yeah i can see that it could have been a few percent better but the i don't think there's a customer that will ever notice what i can notice no problem and so i don't think i can get any better at that than that with this particular color so i am satisfied you know i'm satisfied we've done the best we can do um and yeah it looks looks really good i'm quite pleased so it's a lot longer process than i thought it was going to be yeah um basically like just painting a bike filling it in and then just going through all the steps that i kind of went through when i was doing a diy painting yeah that's and that's a long process definitely and you appreciate it because you've been there and you've been so patient with things like that letting it dry yeah come back to it yeah yeah you kind of have to put a day aside to do one of these you can do other jobs in between but it's going to be your main focus for the day um so you know yeah from from your viewers point of view if you've got a chip and you go to a painter don't expect it to be really cheap because as you can see it's a lot of hard work yeah definitely but the results are worth it you know this customer get the bike back they'll never know they won't even remember where the damage is you know they'll look and they won't be able to see where it was and that's the aim really if the customer can't say oh it was there you know the customer get this back and they'll probably won't even know what side the bike was damaged um so that's new and that's what you want yeah definitely so obviously this is how the professionals do it quite a long process and probably not everybody has you know all these different tools that you've had to do this is there a way that maybe us at home can do it diy style well a cheap and cheerful way to do it yes there is and you kind of threw this on us so i got bex to dig out her nail varnish bag and we've got a chip on one of my bikes in here and i'm hoping she's got a nail varnish in there that's going to be close enough for us to be able to do a little something that shows that anyone with the minimal of bits and pieces yeah can succeed in making a chip look better obviously this standard but something yeah definitely yeah take your eye off of it yeah hopefully we can achieve that let's go do it so this is ali's very nice bike that he's got here but he has got a chip in it so this is what we're going to try and fix diy style what's first so i've got a very fine piece of sandpaper this is 2000 grit all i'm going to do is very lightly go over the area where the chip is just to make sure it's clean and got a slight key for the nail varnish to adhere to this is obviously quite a small chip compared to the last one yes we saw would this diy kind of stuff work on a deeper chip or definitely definitely i mean we could fill this chip with a tiny bit of filler yeah but i'm assuming that most people don't have filler at home so um i'm also assuming that most people probably do have nail varnishes at home so we've got a white now varnish it might not be exactly right but it's going to be better than this um if you haven't got a color anywhere near you could always just dribble in a clear bit of nail varnish and that would protect the paint you know protect the chip stop it wanting to chip anymore so i've just give that a little bit of a key um and i'm going to use a paintbrush rather than the brush from the nail varnish and this genuinely is the first time i've done this so it could go horribly wrong but you've used nail varnish before all the time all the time you can tell by my nails what i'm going to aim to do is just put a dab of paint in hopefully not too much and then we'll walk away for a few minutes let it dry and come back and put another dab of paint in so one coat done and dried yep how many coats are we looking to do don't really know the chip's not really deep so hopefully only another two more but it's a bit of a wait and see so guessing game yeah two coats later i think that looks pretty good yeah yeah i think i think we're proud of the paint surface so next stage now is to smooth it back a bit so the idea now is just to get that now varnish at the same level as the paint around it well in my eyes i think that looks pretty good for a bit of nail varnish i know it's not up to your standards but yeah no i mean what it shows you is you know don't be devastated if you've got a small chip or scratch on your bike you know there's always something you can do to take take your eye away from it more than anything else um and at the end of the day it's protected it looks a lot better than it did so there you have it that's how to fix scratches and chips on your bikes at home if you fancy doing yourself and how the professionals do it again a big thank you to ali and bex for showing us how it's done today and if you did enjoy this video and found it helpful then please give it a big thumbs up
