Paint: Sikkens makes a putty for filling small imperfections before painting. It is called Kombi Putti. It is acrylic rather than lacquer based so it won't shrink. The suggestion to use PPG epoxy primer is something that I always do. It comes in a variety of colors including black and can be top coated with any automotive finish. I use it as a base before my urethane primer filler and as a sealer before my top coat. Great STUFF!
