The Zmax ads have really increased on Speed and ESPN 2. Not that I'd put the stuff in my ST but with the high profile folks endorsing the product, does the product really have merit? The ad with Carroll Shelby is pretty corny, but I would think he stake a reputation without the product actually doing some good. I remember in the early 80s the product Slick 50. Now looking back, I read it was nothing more than snake oil and didn't do anything as advertised.
