I painted my Plymouth a few months back with Single Stage Urethane. It ran pretty good. This is a resto I left it for a bit got tired of body work so i moved on for a bit. I plan to sand it back down. Ive done all the body work on this car but im not an experienced painter. I need to buy more paint and was thinking about going with a Urethane Basecoat system same color. Can i get away with just sanding the car back down and shoot the basecoat? Thanks!
