I have an SC430 silver coupe with factory chrome wheels were the dealer had the chrome center pieces chromed to match the wheel. I washed the car always and waxed the chome wheels with Mother's chrome polish and all 4 wheels now hae surface scrateches. Any one have similar problems and know what I can do to get the scratches off or do I have to buy 4 new center chrome pieces. If so, where do I buy them. There is only one dealer in Memphis and he does not know where to get them. I bought the car in Chicago. Thank you.
