Can I apply P38 over a painted enamel surface?
II have a GRP panel (boat roof) which has been coated with layers of enamel. Most of the paint is in good condition however some areas the enamel has peeled off and more enamel just painted over which has left a rather ugly uneven painted surface. Can I apply P38 over the enamel painted surface and flat off? Will P38 bond to the painted surface?
