No one has ever mentioned this product on the board since I've been here so I thought I would chime in. Those of us that rebuild antique vehicles have used these as long as I can remember as these were around many, many years before the California Duster and are actually used to dry wash vehicles without making scratches. check out the link and go to the bottom of the page for the FAQ page link. Enjoy!...Michael P.
