I just got some free supplies from a friend who has cleaned out his garage, the only two items that seem usable are 3M Mircrofinishing Compound, which I think is med. cut, and GS-27 scratch remover
For the 3M, should I use it? My car is still extremely filled with scratches, should I apply this stuff by hand, not the pc? Also is that gs stuff just a filler, should it be applied (if at all) like IHG.
