If your nail catches the scratch or chip, the only way to fix it is to repaint it (ie touch up paint). Polishing won't do much unless the scratch is on the top surface and didn't go through.
I detail my own car but I know of a couple detailers around the south bay but unfortunately they are not Adam's users. Although they do good work. I'm sure they would be willing to work with you if you have the Adam's products in hand. PM me if you want their contact info.
