My dads car was actually damaged by a touch car wash. One of the brushes caught on the edge of his hood and folded over the hood metal. It was a huge pain, had to fight the car wash company to pay for the damage (they eventually did) and even still you can tell where it was repaired. Plus they wouldnt pay for color matching so he had to pay out of pocket for that.

Between that and the possibility of some tiny rock or grain of sand being caught in a brush and scratching the heck out of my car, I now only ever use touchless or wash it myself if the weather is warm. Im in upstate NY where we get pretty cold winters, so whenever it dips above freezing ill run through the touchless just for the underbody spray to get the road salt off
