Pangburn

Does anyone know where to find some of the clear film that's used between the ground effects and the sheet metal right in front of the rear wheels? I'd like to find some and use it to line the sunroof opening to try and seal up the last little wind leak I still have. My theory is this stuff is pratically invisible and holds up to the worst environmental crap you can throw at it (rock salt, slush, burning rubber ) and should hold up to the sunroof glass weatherstrip sliding up against it.

Thanks in advance for any tips.
