As a rule, never use anything on your wheels that isn't safe for your paint.
This is very important when dealing with wheels that have an anodized finish, such as many different Volk models.
Personally, I suggest you use Sonax Full Effect like a poster above mentioned. This is a great product that breaks down dirt and brake dust over time before you then wash it away. If you're interested in wheel protection after the fact, something like Wolf's Rim shield is great.

IMO, it's best to go ahead and order from an online vendor such as detailer's domain, where you can read about proper use and application for the product rather than paying out the *** for an inferior product from Autozone.
I'm not saying that Autozone doesn't sell some decent products, because they do. However, you're paying a pretty high markup for a product that usually doesn't fit your application 100%.
