Sand them down and paint 3 times then clear 3 time. 180 grit is not gonna make a dent... take too long go down to 120. You don't have to sand to bare metal... just rough up the paint surface.
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

Yeah I just scooped up a nice variety pack from the ole Home Depot
The wheels have a nice metallic finish already, I just am not sure if I should just try to take like all the clear off and then go apeshit with some 1000 or something and try to get a nice polished finish or just go with some "alloy" look paint.

Don't know if this helps or not, here is a picture of mine which I had refinished, polished lips and painted centres. I had mine done by a wheel reparier, so I can't offer any advise as to how you do it though, sorry. Good luck with your project, and post some pics when you are done!

jrobbo what color code did you paint your calipers with? is it "caliper paint" or just high temp spray paint?

It was just silver caliper paint that I picked up at the local auto-parts store, I can't remember the brand, but I will take a look when I get home from work. I don't know the color code, but they only had one type of silver.

I'm not doing M-Pars, but style 5's. I did one already. Same issues as you, with the cracking, chipped clear coat. Planned on using Wurth clear on the wheel & Duplicolor silver # 378 on the center. Here's the route I took.
- Separate the center from the rim & removed tire
- Sprayed down the rim with this stuff called "Peeler" that I picked up at an auto paint supply shop. Not as harsh as other strippers they typically use
- Wire-brush cleanup of the wheel center mating surfaces
- Blasted the rim with power washer to get all the old clear off
- Now here might be the big mistake
- I did NOT sand down the rim, I used Mother's polish. Well, the three coats of clear did not stick. I was afraid of roughing up the aluminum, so I stripped it off again & just polished it
- Polished the bolts using a wire wheel on one drill mounted in a bench vise, and the bolt in another drill, then ran the bolt through more Mother's
- Re-sprayed the center with the #378 silver, then three coats of clear
- Re-assembled the wheel, tightening & torquing in a star pattern to 30lbs
- New Kumho Ecsta AST's
I just drove it about 850 miles to DC & back, averaging between 75 & 90 MPH. No issues with wheel balance or out-of-round after reassembly. However, polishing vs. clear-coating will make it hard to keep clean, but when they are clean, they shine nice It's amazing how nasty those bolts get.

I know mine are only standard 15" basketweaves style, but same theory..
The paint was very thin on mine - a good hard scrub would take it down to primer in places, so I decided to go for te polished lip & dark centres..
Started with Nitromors (paint stripper), got all the paint & primer off the lips.. unfortunately the rims are a 'crinkle' finish under the paint, so out with the 120 grit paper to smooth them down.. This was the hardest part of the whole process - more just time consuming than real hard, but it'l give your arms a good workout!
Once all the 'crinkle' was gone, I used 400 grit wet, to remove the harsh sandpaper scratches.
After the 400 grit, I used a Brillo pad (soapy fine wire wool, for doing crusty pots n pans, dunno if you yanks have them or not!).
The finish you see in the pic is straight from the brillo pad (ok, so I masked & sprayed the centres too in dark grey metallic), it's pretty shiny & scratch free but using some polishing compound on them willo be the finishing shine I think, just to take out the final very fine scratches..
Each wheel took me around 5 hours start to finish (so far), including waiting for the paint stripper to do its stuff..
Hope this helps!
