http://www.prowax.com/ There's a dealer in my area for these products. I've used the Clay Away 3 clay bar & S-74 Wipeout system on my vehicles and it works nicely. I wouldn't normally use such an aggressive clay, but I work in an industrial area, and our company in particular does a mass volume of outdoor painting. How do their other products such as polishes and waxes compare to a product like Optimum? Are they worth using as well? Just wondering if anyone has had any experience with them.
