Every once in a while when I roll down my drivers window all the way, then bring it back up there is this black grease steak at the top of the window extending down about 8-10 inches. its a very fine and very thick steak and its always in the same spot. I then have to go get a paper towel and wipe it down real good to get it off.

Anyways, does anyone know what the hell is causing this? I want to get my windows tinted but Im nervous whatever is rubbing up against my window will ruin the film...

Take off your door panel. See what the problem is and go from there.

 

Yeah I gotta take em all off to do my leather inserts anyways, just thought I'd see if anyone else had ever had the same prob...
