I am new at this painting. I am using KP-2CF Epoxy Primer. I sprayed on 3 Coats and it has the apperance of Orange Peel. Anyone know why? I am using a gravity feed gun at about 20 psi air. Tried less preessure and it was worse. Sanded it smooth and reshot, and same thing. Is this normal? I am still practicing, doing test on a old hood. I am painting bare metal.
