I have a set of Non-OE M-Pars lying around with some severe clearcoat oxidation. Two of the wheels look great and the other two are bubbling up and peeling every which way. I was just going at one of them with some 180grit and it felt like it wasn't doing a damn thing. Just curious if you guys had any advice, as I've done my fair share of painting **** before, never a set of wheels.

Questions:
- What grit to use for different steps?
- Should I PAINT the wheels, or just sand them nice and paint on a new clear?
- Any advice or experience you have is much appreciated
