When I had chrome wheels on my truck, I used Mother's Chrome Polish, then buff, then wax with Meguiars Gold Class once or twice over, and buff them out again. I also used the Mother's Power Ball from time to time. Always polish, then seal... it's like a car, you wouldn't wax over improperly cleaned/prepped paint... that would only seal in unwanted contaminants.
thanks I used the chrome polish after washing them really good looks sweet. I have to over wash my car as I live on gravel roads and don't want that gravel dust sitting on the rims for any amount of time so I wash my ca at least once a day
