I recently painted my 96 z28 the clear was chipping very bad so I sanded the entire car and shot it with BC\CC well it looked great until it rained the next day. it had deep blue waterspots under my clear I freaked out dummy me started tring to sand them out of the hood only thank god, it wasent doing any good so I had to work the next couple days the next day I was off I went out to look at it agan and the spots where all gone I was very happy they where gone but i still have to redo the hood because i went through the clear. I sanded the hood and shot another basecoat on it all around the spot I went to deep was wrinkeling up looked bad,I think it was because the solvents in the new paint caused the first base to soften, any suggestions I can solve this problem?????? Do u think if I sanded than shot sealer over the intire panel would help???

 

any pictures of the wrinkling? what grit did you use to sand. did you use any wax on your car after the first paint job?

 

You'll want to sand it back down and hit it with sealer before respraying. The reducer (solvent) is attacking the existing finish and causing it to lift at the edges of your sand-through. You didn't mention how much time elapsed between the original paint job and your attempt at respraying the hood. Generally that happens if you've tried to recoat too soon. Not sure what brand of paint you're using, but I've found DuPont to be less forgiving in a situation like yours, as compared to PPG. Honestly, though, shooting color directly over a sand-through isn't a great idea anyway, because it will often leave a funky looking ring even if it doesn't lift. As far as sanding through, I recommend no less than three wet coats of clear to prevent this from being an issue. If you can't get a reasonably smooth finish, you may want to do four coats. It's nice to have a little extra film build, just in case you get a scratch later on that requires a sand/polish. Any questions, let me know.
