i have a 02' tahoe and i tinted the windows, before my tahoe i also had a 00' z71 silverado same body style and with both i had a problem with my front windows scratching. i tinted the front windows and from rolling them up and down there is a very noticeable line in the same spot in both vehicles straight down the window. i was just curious if anyone else has had this problem and might kno how to fix it. thanks. -Jeremy
