Someone I know clipped my car while pulling out of a space today... it isn't that deep, probably about 1 mm or so. I don't know if the damage can be removed using compound and a little work, or if it needs to be painted. Any advice? I don't want to make him pay for an expensive paint job if I can just buff it out. I don't think touchup would work, as the upper gash is about 5 inches in length, the lower one is probably 2.5-3 inches.
