This is just my thought on this, if I'm wrong I'll say I'm wrong.
I have a 2000 with stock rims. The rims are clear coated with some type of heavy duty clear, maybe some type of clear epoxy?? I think most of what everyone is seeing is just the clear chipping off. Mine are doing the same thing. If you completely stripped the clear off, put some aluminum cleaner/acid on the rims to get the aluminum looking good and recleared the rims, would this be a fast "fairly easy" way to get the rims looking good again?
I was a musician for many years in a road band. We had a pretty big light show that went with us. The truss was built out of aluminum. About once a year we had to clean the truss. I don't remember what the stuff was called but it was some type of acid for cleaning aluminum. It worked really well. We did not clear coat the truss we just cleaned them. They get dull looking again and we'd clean them again.
Just brainstorming.....:hmmm:
