I put Nanohide Ceramic Coating on for my paint protection and use them all the time. If you have ceramic coating, use the cheapest wash possible, you dont need all the goodies like wax. Wash away!
I hand wash whenever I can but when its too cold to do that and the car is just too dirty I go into a touchless car wash that has no rails. One by me you pull in and park and it swings around. Does a crappy job but it gets the salt and stuff off in the winter.
I hope to find a good local guy that will come out and hand wash while I am at work or something.
I havent seen many touchless washers here in the DFW area but also havent looked too hard as I havent spoiled my current cars like I plan on doing to the Tesla .
