They told you not to come back??? Hell I've taken my truck in to many car washes and its been 100 times worse then my quads and I have never had a problem. I always sprayed the mud into the drain tho. They didn't care as long as they didn't clean it. It was alot of mud to...Yeah I've done that before with my old blaster and I was kindly asked not to come back. I did a quick search before I posted on this thread and it looks like everyone is using purple power and mean green. Guess I'll give one of those a try
