    Hey guys I've been working on the paint on my car and I can't seem to get the lines right after wetsanding. How can I get rid of this blotchy look? More clear coat then wetsand? or?
    It doesn't have to be perfect, I just needed to get rid of the flaked rusty sections.

    Thanks

    i believe a wet sand, clear, wet sand again, then buff would do the trick.

    Its important to wet sand in between coats for a smooth finish. If you dont, youll get orange peel as you have there.

    Looks like you sanded through your clear coat and into your base. You are looking at a respray at best. If you clear coat it you will just highlight the fuckup.

    Stock clear coat was real thin. It isn't into the base surprisingly, no colour on the sandpaper.

    As a note, that line is the separation of overspray, actual spray, and stock paint

    This. You went too far. It needs to be redone.

    So there was a blended paint job done on a fender? There will be no way to hide that line or get rid of it unless you feather the line with 600 and respray some base/clear.

    Good tip, thanks. I'm not looking to totally hide it, just minimize the appearance of it really. This is after wetsanding 2000 grit on the clear coat blend line

    Hey guys, I clearcoated over it, looks good so far tbh, you can see the line a bit but I'm going to wetsand later to see how I can change the dotting orange peel from the spray can life. Not bad overall

    I think you need to go slower and be more careful. Going through the clear coat twice is nuts. Spray about four coats of clear on. There is no need to wetsand between coats. Once your clear is dry, wetsand carefully with 2000. Once the water turns milky, you have started to remove clear. There is no need to sand that section anymore. Repeat with 2500 and then 3000. Then use a buffer on around 300 rpms with some compound and slowly and lightly feather the new clear into the old. Do NOT overheat the panel or burn through again. I admire your unwillingness to give up. You can watch some Ammo NYC videos and Kevin Tetz knows what he's talking about too.

    this.

    Only wet sand until it the water starts turning cloudy. The way i always have seen it, the more clear you add, the more times it can be buffed in the future. I usually do 3-4 coats of clear on body panels.

    Wet sanding in between is just for ideal finishes, dont do it for some fixer uper work, more trouble than you need.

    It was only once, first one was not actually thru clear. I think I have too many layers of clear lol, paint still isn't coming off, there's just an indent where the layer peeled.

    Yeah I was definitely being a bit of a perfectionist and actually messed it up this time. The overspray got to me!

    You can see that the clear is missing in the last pic in your first post. Either that or it's a terrible picture. You'll know when you're through when the paint is a completely different texture. There is little resistance to moving your finger across it, whereas the clear likes to create a lot of friction when you drag your finger across it. Ask me how I know. Once or twice, it doesn't matter. I don't think you can put on too much clear. Unless you sprayed like ten coats on. Even then, I'm not sure that it would be something bad. Using spray cans also makes it harder. Not impossible, just more difficult to get the clear where you need it. I'd mask off the whole care to avoid overspray, even if you're doing it in the garage.

    I also wanted to add to my last post that this isn't a permanent fix. The clearcoat will never flow out and bond with the existing clearcoat on the panel. This will just look good for a year or two. The only permanent fix is to repaint the fender. Oh, this is a rear quarter. Well, still, the only permanent fix is a complete sanding and respray (not the whole car, just the body panel, which I believe goes above the doors all the way to the front fender).

    Thanks for the advice. This is more of a patch to get me through winter, the pictures are actually of the front fenders and I'm thinking of clearing the entire thing.

    Oh sorry, looking at things backwards and too quickly. Yeah, when you get ready to do the whole fender next spring, just take it off. Should be a piece of cake for you by then :)
