I've always been fairly impressed with what I've used on the ValuGuard line. You can tell that it is designed to be used by detail shops that are faced with a zillion problems. Some of their polishing compounds are really nice to use. I know that shop grade products aren't talked about a lot on Autopia, but these are some that are worth looking into if anyone is interested. I'm looking forward to writing a review on the new car prep.
