Ya, Tint Protector
sell the BMW felt kits. Some people say ceramic tint doesn't scratch but that's bull. My M3 had a super high end 3M ceramic tint put on and in less than three weeks I saw vertical scratches all over the drivers window.
I put my window down almost every time I'm in the car though.
After I put on the Tint Protector moleskin and had the drivers side window tint replaced under warranty NO MORE SCRATCHES!
