If you are talking about the automatic touchless car wash in a town, it will not damage the paint, but will strip all the waxes...

In order to clean the car, get a rinseless car wash products from chemical guys, ONR, or other detailing companies, and do it yourself.

Go to youtube and search Gary Dean's waterless car wash method. It is much better than the touchless wash machine

Absolutely the worst thing I ever used on my old GTR. It was swirls galore on my black paint. I can see it work on silver or other colors which hide swirls but nonetheless damage is being done.

It depends on what kind of method you are using...^^ I have used Gary Dean's method + some add on and it works great

Also most of touchless or waterless washes are for light dirt..not like heavy dirt...Always wash by two bucket method if it is super dirty..^^
