has anyone used one in a carwash and do they work ok?

I am one of the few that use the Viper Shine machine. I like it because there are no moving parts. Upside - less initial cost and less maintenance. Downside is cost per application is higher. Nothing works as well as hand application. But it works well enough to provide a noticeable effect.
