I have 17 inch rims . And the crome is starting to chip off. I would like to strip them and have them power coated white. I took them to a shop in nj that power coats. The guy sand blasted one rim. He got the crome off, but also ate grooves in the rim. Any one know a better way to remove the crome? I don't trust letting this guy sand blast my other 3 rims.They are aluminum under the crome.Can they be asid bath to remove? Thank for any info mike s.
