Clay Magic followed by 5-Star. 5-Star is an incredible product. Supposed to last for 5 years. PFTE based product to which nothing will stick to. Found it on the "Links" page, and decided to try it. Kind of a pain to apply, but has worked perfectly so far. I wash with water only, and everything comes off usually with the 1st rinse. Everything not taken off with the hose comes off with a slight rub with the mitt. Even Tar!
