I got a model y 6 days ago. My sister also got a model 3 in DEC 2018. She and her husband were saying only use touchless car wash. The beaterrs scratch the paint and mess with the cameras. I'm in Chicago Suburbs. Not sure which are touchless. I stopped by waterway and he said we get lots of teslas every week and the beaters do no harm. And if you add wax it counters the scratches. My mom said that is bs. There is a car wash mode but that messed up the GPS and cameras somebody in another thread here said so. I hope that never happens to me. Are there any touchless near me? And anybody else use aaterway? Are the brushes bad for the paint and cameras? Or he was right and wax fills in the scratches?
