Just something else gimmicky to sell, service, and supply chemical to. Motorcycle sales soared last year and someone trying to cash in. Every bike owner I've ever known avoids rainy travel if at all possible, so good luck finding alot of dirty bikes out there. Also, check the odometer on your average motorcycle...very low. Low mileage equals garage kept and not much road time for getting dirty. I caught they mention a 'cool down' pass...sure...that's carcare 101, don't spray cool water on a hot engine. Cracked heads and engine blocks for everyone.
