If you have done any mods at all to your rims.my are powder coated and polished.no clearcoating.when it was at the dealer the lot man thought he would clean my rims with a watered down cleaner.he cleaned like he would a steel or chorme rim spray one rim then the next and so on.it stained all four rims.they had to have the tires taken off and polished again.they looked as look as before the issue.however it is just stressfull.a honest mistake and fixed.lol
