There is another thread right now going on, on fixing a scratch on their bag. Same problem. Finding some one who will even do the job. It's expensive. There is a lot in the past on this too, search is your friend.

You could also look at bringing them to a shop that will do the job, either the paint or plastic wrap, they are popping up everywhere here for cars. I added some wrap to my black/red IS trunk, to cover the red, since I mounted it on my black/cream ACE Tourer.
