As in the paint layer has a few scratches?
Some remedies that I would try, keep in mind that once you do you can't undo...
-Go over the scratches with as close a color of sharpie as you can find
-or with as close a color paint as you can find (difficult to get on precisely though)
-probably your best bet, would be a few coats of Spray Clear coat. Goes on like a mist of water, a few coats and you will have a very thin glossy clear coat. It ended up yellowing a tiny bit in one area when I used it on a guitar hero guitar, but that was because too much pooled in one spot. I have the Krylon brand Clear Polyurethane spray, color "GLOSS" number "7005"
Hope that opens a few options for you
