scratches :@

Well I would say getting scratches out of your plastics is alot like repairing scratches in most things. Pending on how deep they are you could start off with a 400 or 600 grit sandpaper and keep stepping up to a finer grit like 800 to 1200 to 2000 to 2500. You could skip through and do every other it just would be harder to get the scratches created by the last grit out. With getting it up to 2500 grit, you can use rubbing compound by hand on a soft clean rag or if you have a buffer (don't get it too hot it'll warp). Hope this helps, I've done it on tons of things, glass, headlights, clearcoat and other plastics. I'm positive it'll work on you quad plastics. Hope this helps buddy.
