If it is the same thing I think you are talking about, I had the same issue when I purchased my coupe. It was on the inside of the glass and looks like scratches and would not "wash" off. It kind of looked like a wax build up but with a little elbow grease, it did come off. Just using window cleaner did not do the trick, you have to rub pretty hard to remove it. Even after getting the smudges off, everytime I rolled the window up and down it would leave a little smudge but after a little while...it stopped. Guess there was something like a hard rubber molding in the door/window track that needed to wear down.xorcst wrote:i have an 08 Altima 2.5s Sedan. i've had some scratches that looks like ////// ////on my driver side window. at first i thought it was some strange rock that hit it and made the scratches, but i believe that it has gotten worse.I'm thinking that is a gear or something inside the door that made them. so I'm wondering if anyone else has had that same issue...
