damn, those ARE some awesome discs! wow. I saw this link on his site, and there's a bunch more awesome dye jobs. I don't know how this guy did his, but it almost looks like they were airbrushed on.
wow, I think I like that page even better. If he is doing them with regular masking he has got some time on his hands. I have a bunch of extra discs laying around. Im going to have to try a few simple jobs and see what I can get in to.
