I am planning on purchasing a PC here shortly. My car seems to not quite shine like I would expect. The car is fairly old and new to me. I am assuming this is probably just some sight oxidation. It also has some minor to moderate swirl marks in it. I've heard a lot of good things about Poorboy's. So, I was thinking about using the Poorboy's SSR2.5 followed up with the SSR1. Is this is good series to mainly remove the oxidation? Or is DACP a better product than the 2.5 for oxidation (I read that in another post somewhere)? Thanks for the help.
