P21S Bodywork shampoo

Have been using this stuff for the better part of the last 15 years and swear by it. Yeah, its more expensive than just using dish washing liquid on your car, or even the el-cheapo stuff at your local auto parts store, but its worth it. Brings back the luster to your car. I know this is highly recommended by BMW and Mercedes. I've never owned either one of those and I can tell you that it works just as well on Hondas and Toyotas
