I recommend anyone to stay away from touchless car washes. High pressure washer cannot be good for your paint especially if have small rock chips. It can chip the paint that is already weak. High water pressure can also create micro cracks in your paint.

I am still not convinced that brushless is that bad. Brushes are made of similar material to the ones used in a mitt. Recycled water should not be a problem if the filtration system works well and can capture fine particulates. If anything I see that a brushless system will work better than a hand wash--water is constantly poured onto the surface. This helps wash dirt off that would scratch your car and ensures that the surface never dries out.
