Not sure what happened, I just got them a few days ago and I just noticed. Some of it peels off if I try. Could it be plasti dip or something of that sort?That center cap is also peeling/fading and I doubt it was painted at the same time and place as the wheels. What the heck happened, did you somehow get a chemical spill on the wheel?
Okay I’ll give it a try, thanksI would try the lightest polishing compound you can find at a parts store and try in a spot that isn't too obvious. Put it on and wipe it like wax. Even those splined Gorilla lug nuts look really faded and odd, and I tell you they are GLOSS black when you get them new (I just got a set).
Try a very small part with light compound...
