Hey... yet another post from me =). I also have a problem with windows streaking... I believe it is from one of the components inside the door rubbing against the window when i roll the window up and down like I said I have a 05 Mustang GT... I got my windows tinted and then it was worse cause I see it more now and i'm hoping that it does rip my tint off because they don't cover that kinda thing. I heard others were having the same problems with their mustang... did anybody find a fix for it yet?
