I've never had a problem with drive through car washes. I usually avoid them. I've only used one twice, but no issues.
New one on maricamp good,or no touch?
3M suggests that you do not but I can tell you that most clients do go through car washes. You want to stay away from Car Washes that tend to be dirtier and stay away from having a pressure washer jet to close to the vinyl.
