I am no painter, but am pretending to be one.
Yesterday, after days of filling pin holes, careful prepping and priming, I shot an Acry-Glo Silver Gray color coat onto the wheel pants of my RV. After mixing, I filtered the paint through a paper filter en route to the gravity feed bowl fitted to the paint gun. I applied a tack coat, waited about 1/2 hour..... applied another coat....waited another half hour...with NO bumps to be seen....then applied the final wet coat. From a few feet away, they look great with a nice "wet" finish look. Unfortunately, upon close up inspection, the surface is flecked with many "bumps". It feels rough when you run your fingers across the surface. Several days ago, I shot the empennage tips using the same product and they turned out perfectly. My questions are these. What might have caused this? After a few days of curing, is it possible to wet sand the bumps out, yet still retain the paint finish's brilliant "distinction of image"...or luster? If so...what grade of sandpaper should I use? Or should I rescuff the surface and try again? I am willing to do that if necessary, however, would be nice if I could trace down the cause of this problem so it does not happen again. After all, that paint ain't cheap, even if I am applying it myself.
