| I just had a question on single stage paint. I'm restoring a 62 vw for my inlaws and just painted the engine cover (first time painting) with two coats (med). Turned out good but I see a couple small pinholes ,looks like solvent pops. Is it ok to wet sand, clean and shoot another coat or two on it? |

| It is a fisheye caused buy oil. Use fisheye eliminator. You will need to fill the fisheye or it will be a low spot. |

| Should I fill it in with a toothpick with paint, let it dry, wet sand it, and shot it once more. The guy at the store said I wouldn't need the fisheye eliminator because its not hot weather or high humidity. |

| Find another shop. Fisheye eliminator is used to eliminate fisheyes caused by oil, wax, silicone etc.... Do not remember humidity, or hot weather having anything to do with fisheyes in paint. I'd sand it down prime the area and a little spot putty. |

| Seems like alot of hassle to sand the whole thing down for two tiny pinholes you can only see up close. Thought maybe there would be an easier way to fix this peice. I'll get the fisheye eliminator for the rest. thanks for the help. |

You won't be able to fill in pinholes with paint material. To make it look right even if they are very small would require some sanding and repainting.
you could just sand it down until the pinholes are out and reapply some paint.
Although an engine cover really isn't that big of a piece, I'd just do it over again. Shouldn't take you long at all, even with priming, etc.
For reference, solvent pop and fish eyes are two very different things. solvent pop comes from either not enough flash time between coats, improper solvents to begin with in your climate, or excessively thick coats. Looking at your signature you're from illinois...I'm guessing this was painted in your garage at home recently? Being that its cold as hell outside I'm guessing your garage(?) is cold as hell also. You probably got solvent pop from using too slow a reducer and not enough flash time. The paint was still too wet before you went on to the second and additional coats. A faster reducer (typcially used in temperatures 60 or below) will help this problem too.
pinholes are more commonly from improperly mixed body filler, not fish eyes. Fish eyes look like craters. |
