I use one on my Saleen and on my bike. Works pretty well as long as the car isn't too dirty. Good to use b4 u put on a cover to keep stuff from getting scratched.

I got it pretty cheap at WalMart.

There's a company out here in Chatsworth, called C4 Motorsports. The make a special duster that works excellent. Might want to give them a call. C4 stands for California Car Cover Company, if you're wondering.
