What all tech stuff do you turn off before going to car wash?

[Rufus]

You mentioned the touchless car wash left pressurized water lines, do you mean the water drips down the paintwork , and left a dried water line ?

What I meant was one of the nozzles was so strong it left a pressurized line on the clear coat, much like when you power wash a walkway

Doesn't sound very "touchless."

EXACTLY But luckily it was rather light. Just enough to catch light reflection which is why I polished it out. No longer visible, even under close scrutiny
