The dealership that I detail for just hired a moblie car wash service that only Sprays the cars off and chamois them. No washing at all. They don't seem to believe me that this is what is causing the TERRIBLE swirl marks and scratches into the cars. They seem to think that this can't be advioded or prevented. The cars are going to hell and I am upset to see my hard work ruined in the space of an hour. Convince me that this is indeed the cause of the scratches etc.
