Stevo - I've had my crossfire for a month and went onto meguiar's website to get some gold class endurance for my wheels and saw that wax for the first time.
Zachhendershot - thanks for the info. I'll probably be picking some up soon and trying it out on my new crossfire. I've always owned black cars until this one and don't know how noticeable the difference will be when waxing a silver car, but guess I'll find out soon enough. THanks.
