Greetings All. Recently I decided to put aluminum discs onto my Ford Sedan. Trying out a different look. Today I went a local cruise and found out no matter what I did, I could get "white" lines out of one of the discs. I tried yelling at it, cursing at it, hell I even tried to clean it with tire cleaner. (Trying to not use anything too caustic or abrasive.) Nothing seemed to work. Any suggestions on what some of you folks use for full discs. If it matters, the discs are the clip ons, not the bolt ons. Much thanks for any suggestions and assistance. I also purchased an aluminum cleaner and have not tried it yet .
