I used krylon fusion camo. From my experimentation, it's pretty wear resistant if you follow the directions and paint properly. Also, the cure time of 7 days is critical.
That said, it's not cerakote. It will chip and scratch, but I don't mind a little wear on the paint. (Wear on anodizing would suck)
I don't want it to be permanent anyway. I like the fact that I can completely remove all the paint without much trouble. You can't do that with duracoat, cerakote.
