I don't think OCP is going to cut it if the paint is that bad, espicially via PC. If it's really *that* bad you might want to look into Optimum Hyper Compound, otherwise at least use regular Optimum Compound. After compounding, those products will finish up really nicely. RMG\Blue Natty's, in particular, is a really great combo on black (I use that combo on black customer cars that are not garage queens, garage queens get Souveran).
