I would say that there isn't...even if the brush is safe on your paint, there's gonna probably gonna be dirt or grime on your car that will get rubbed against your paint and cause scratches and such. What I do is make sure to brush off and scrape my windows, and then brush the snow off my car, but I don't brush it all the way down to the paint, I leave about .5" of snow on top of the paint. That generally falls off by the time I've pulled out of my parking lot or by the time I've got to the main road.
Great. Thanks for a response. I was wondering if there would be a brush made similar to a squeegee some use to dry the car. The soft rubber materials may be pliable to lift snow but not scratch the paint. I guess the snow am ice do most of the damage on the clear coat.
