has anyone used this stuff? The ad claims you just need to wet-down your car, then spray it on and lather the dirt away with a sponge.

Sounds like a real good way to add plenty of swirl marks to me. If you need to rub the dirty surface to lather the soap, then you are also rubbing the dirt into the paint.

If your car is dirty enough that Final Inspection (Quick Detailer) or a like product is out of the question and you must use a hose. The only way to avoid (hopefully) swirl marks is to use lots of water and flush, flush, flush the surface as you wash.

I would just stay away from that stuff, because the only safe way to wash your car is with plenty of water and alot of soap suds. Sprayers with soap and water only create friction to scratch your paint and make swirls. I say if we are lucky enough to own a Mercedes-Benz lets not ever get lazy about keeping them perfect.
