Just got 20% tint on my side windows, it looks amazing but the film squeeks whenever I roll my windows down and it's incredibly obnoxious. Any ideas on how to remedy that? Already tried cleaning the insides and lubricating them with no success.
Try Rain-X (great stuff!) or Gummi-Pfledge from your local BMW dealer. The BMW stuff is a rubber/weatherstripping lube/protectant. Rain-X is a silicone-based liquid that helps to repel water on glass. Rain-X applied (properly) to the windshield is awesome, imho.
Post pics, please. I'm thinking of going with 20%.
I've always heard that you should wait to roll the windows up or down for a few days afterwards. Like previously said, all you need is some lube. That's what she said.
