yeh scratch x and 4" hard pads work well, i removed some deep marks from other car, but it is sometimes better to do bird lime with hand and alot of rubbing (with scratch x) , although the paint was softer.
the sfx polishes are worth ago, and there only $6 ish when bought with pads, if you get sfx 1 get to though
