I haven't used it yet, but I know several guys who have. What is it? Clay for cleaning paint before you wax and or polish. Check out Griotsgarage.com for all your car care needs. I am not as good at taking care of my vehicles as I should be, but I recently started using some of their products, and am pleased. Soon, I will try the clay on the SVX. It won't help the chips on the hood, but as for the rest, we'll see. They also give good advice on car care. Apparently they do concourse detailing and have developed a product line. They also have some nice garage toys too.
