Used my PC for the first time today, though I've had it for a few months now. My boss side swiped his garage pillar with his Tundra. The scratches were pretty deep, my fingernail catches in em. I gave it a shot with the PC, Ultimate Compound, and Ultimate Polish. The PC7424XP vibrates intensely, is this normal? My hands were about to fall off and got tired so quick. Another thing is, I bought about 8 pads when I bought my PC7424XP, is it normal for them to discolor when I haven't even used them once?
Anyways heres the before and after, you guys think more can be done, or are they just too deep to remove?
