Yeah, PP is good for removing that kind of marring. I'd say the PP is a bit more aggressive than the #80. If you use the PP with a cutting pad you'll have to follow up with it on a polishing pad (or maybe MP/polishing). If you use PP with a polishing pad, you *might* have to follow with MP, depends on the paint. FWIW, I prefer PP over #80 myself, but others will go the other way.
