maybe this has been answered before but has anyone used spot putty ON TOP of the rustoleum? I am painting my Corvair- Black on top, Red on the sides. I have 5 layers of black on the car and have noticed some small spots that I missed. Can I apply some spot putty over the paint after wetsanding and then continue to paint over top of it?




Spot putty isn't good unless it's catalyzed/hardenred.. it'll shrink on you. I have put skim coat (bondo mix + fiberglass resin) and full bondo mix over rustoleum, with no problems.
