Not really anthing you can do. Can’t paint it with art pait. You would need a profesional set up to do the job. And for a solid color would cost you like 30 bucks. And you wouldn’t have the nice beadblast you used to have, and most likely, the dings will still be there. They will be painted over but you can still feel them and see them. Just not as well. And you can sand it with a drill. But that can throw the yoyo off and give it a good vibe, and you wouldn’t have the nice blasting surface. You can ano it, but it will cost you like 30 bucks, and it will hide the dings, but they will still be there. You will still feel them, and see them. But you would have to strip the yoyo to do that. Best choice is to just take some light sand paper, lightly rub the dings. Just a little. Just enough to where it won’t totally slow down grinds. And then just pick up the glass, and yoyo. Or just deal with the dings, and just yoyo as Matt said.
