Polishing a set of OE GMC rims can make them look like new again, all you need to do is sacrifice a little of your precious time to actually make your rims look like new again (:
You can spare some time, right?
If you’re going to use either a liquid polish or paste for your wheels, make sure that it doesn’t have anything in it like acid, anhydrous chemicals or ammonia. The reason why is because all of these things can damage your OEM GMC wheels… which is something that I know you don’t want to happen. These chemicals can eventually tarnish the metal; this can lead to the premature aging of metals.
Another thing you should do is make sure you read the directions before you polish wheels; you don’t want to do anything the wrong way!
Pay attention to the directions!
