Iwent through EXACTLY the same thing as the original post. But my tint was a dealer-sold option, and came with a lifetime warranty. Sounds nice, except I have had them re-tint it 4 times, various windows but always the driver's.

"Window gasket" folding inward caused them to replace it every time. I finally asked the tech to take the door panel off and THEN take it to their contracted shop to have it tinted since I didn't want the tint place monkeying with the door. After all that was settled and they weren't pushing the gasket in, I got vertical scratches in the tint in the drivers door. Three times. I was sick of it and told them to please do something about it or replaced the damned door, and apparently they figured out something this go 'round.

It's sucks, but I'm glad to know I'm not the only one with the problem. I've never had tinted windows before and for what the dealer charged for it I wanted to be perfect.
