Hey guys I have some aftermarket rims that came off my cts. They have been sitting in storage for about a year now. I took them out because im planning on selling them to get some rims for the crossfire. But while looking at them they have these weird white things on them. Not really sure what you would call it but they are only on the dish of the rim the stainless steel part. Is there a way to get rid of these things with out redoing the entire rim? Thanks
