Regarding when the tine is freshly installed, I was told before not to lower the windows or risk the tint potentially moving / wrinkling. This was when I had the Monte done up at Superior tint in Milwaukee.
On the beetle, they are frameless windows, so when the doors are opened or closed the window does retract about an inch until the car is started or the doors are locked.
How would this work with the freshly installed tint? To my knowledge, there is no way to turn off or prevent the window from lowering to open the door as the window would be stuck in the roof seal.
