A few auto body questions

Yea what he said lol

I would also suggest that if you have any areas that need filler work that you leave the 50 grit sand scratches in those area's. That will do two things, one, help you see where the dents were after you epoxy, and two help hold the filler on.

As far as spray guns, I use a $10 harbor freight gun everyday in the restoration shop, believe it or not... as a primer gun.. It's one of my best spraying guns to be honest. Although it has been gone through I wouldn't trade it for anything. Just don't leave them in lacquer thinner to clean them over night.... fan adjustment is made of plastic and melts lol...
