Just watched the 4 steps to painting and a couple things were quite different than what I may have done in past (maybe I had it wrong before?). Previously, painted base coat allowed to flash off and sprayed over with clear. New method from 4 steps. Spray base, allow to dry (how long wasn’t really mentioned??? Waiting too long to me would impact chemical adhesion), then sand up to 600 grit clean, tack and spray clear. I had always thought 600 to be too fine and would affect mechanical adhesion?
Just looking to clarify as hope to paint car in spring….26 degrees outside now so not going to work now!!
