brielly Looks like I'll be adding two more coats of clear. Apparently I wasn't spraying the coats wet enough. I just re did the hood and it looks like a sheet of glass. Yup there some runs but at least now there's anough clear to where I can sand them out and not have to worry about it. Now on to the rest of the truck. Thanks for the help.

Art Deco If in doubt put a couple more coats of clear on it.
If its one thing I've learned about finishing paint it's
Put on enough to give yourself the room to level it out.

brielly Ok so I smoothed it out as best I could, shot eastwood silver and then 2 coats of their clearcoat. I got the second coat on pretty good (first wasn't wet enough) and now it looks decent except for a few rough spots on the hood that weren't shot wet enough. I plan to respray the hood to fix that problem. Now the finish of course has some dust in it so what would be the best way to get it smooth and shiny? It does'nt have to be perfect and most importantly i don't want to burn through the clear coat. The clear is probably pretty thin so what should I use to cut, buff and polish to get a uniform shine without causing myself any headaches? I have a rotary buffer and wool pad. I'm guessing I need a foam pad too? And what compounds and polish would be best for the job?

brielly Yup the por was sanded prior to topcoat. I just picked up some 2k glazing putty so I'll smooth out some of the uglier spots and put on one final coat of epoxy.

Lizer looks like it's a little late for that as he's already primed over the POR, but hopefully you scuffed it up good so there was no gloss remaining.

mitmaks make sure to sand por15 to have good adhesion. if you don't whatever you put on top of it will just peel off as por15 dries to a pretty slick finish.

Nah, in a perfect world you would have had the rusted panels completely removed


In the future, put that POR on with a disposable foam brush and it doesn't leave brush marks and you merely pitch the brush when you're done.

If you're just trying to cover up brush marks and it were me, I'd get some 2k glazing putty and it should fill in the brush marks nicely. Sand it down with 180 or 220 and almost all the putty will sand off except for where it filled in the brush marks.

mitmaks As stated above, you need to put filler over deep pits/scratches, etc. Sand filler down and then put 2K primer over it and sand it smooth, finish sanding it with 400-600 grit wet.

Lizer Is it rough because of the rust? High build primer, especially from a can will hardly do anything. To smooth it out at this point you're pretty much left with skimming it with filler and priming again. However, since you didn't remove the rust but just painted over it with POR, you can expect that rust to come back.

Paint Question

Hello everyone. new guy here with a paint question. I'm trying to get a half way decent paint job on an old rusty truck Here's the details. I just got done spraying 2 coats of epoxy primer. It seems to have come out good but there are definitely some areas that will need quite a bit of sanding to make it smooth. Basically while trying to remove surface rust I realized it just wasn't all going to come off so I applied por-15 over those sections. At this point I'm not sure if I should just sand the epoxy then add one more coat or look into a high build primer. I'm running out of time weather/temp wise to do more spraying here in NJ. Would a high build rattle can primer be ok over the epoxy just to help get those areas smooth. Its going to maaco for a final spraying (obviously not a show car) and I believe they will put a universal sealer over it before spraying. What do you guys think I should do to get this a smooth as possible before getting it painted? Thanks in advance for the advice.
