My car is relatively new (2004 Mazda6), but due to some neglect on my part while I was at college my car took a beating. I plan on dedicating a full weekend to washing, claying, polishing, and waxing. However, while examining my paint recently I have discovered minor scratches (maybe cobweb,not sure what they look like) Anyway I don't have enough $ to invest in a PC, so I'm looking for any products I can use by hand to remove the scratches. Any suggestions?
