Scuffing well cured epoxy primer.
I am finally getting ready to put some paint on my car.It has had epoxy primer on for a couple of years, while working on it.What grit of paper is adequate to give good adhesion to this? Also what color of scuff pad would I use in tight spots ?I don't want to leave scratches, but I want it to stick! My plan is to scuff it all, recoat with epoxy,to cover bondo and sand thru to bare metal in some areas,then paint with a single stage flat black.( Not J.D. Blitz Black) Thanks Jim.
