I looked into a buncha different options when I got a new set while back. How much are ya gonna beat on the bike? Is it gonna be a sand only "clean" bike or a ride the crap out of it mud bike? If ya spend the money on coating get the ultra high temp stuff. I think it needs to withstand somewhere in the 1200* range if u don't want them to discolor. If its gonna be a way clean bike high temp black spray bomb will hold up if prepped right and it doesn't get beat on.
