Go to an auto supply store. Get a pack of 1500grit (or higher) emory cloth, and wet sand the spot and surrounding area, dry, then use the 3M fine cut polishing compound mentioned above, and do a final polish/wax. If it did not cut through the clear coat, it will be good as new. I've done this repeatedly to cars I've restored; learned it from a body/paint guy. Good luck with your repair.
