Quick question re: orientation of ClearPlex film?

Thanks, all.

I have a quick question about applying ClearPlex film? Does it matter which way you orientate the film, in terms of say, unrolling it east/west across the windshield, or, north/south? Does this matter? I am just wondering if perhaps it is polarized, and if so, it would matter if you rotated it 90 degrees before cutting and applying.

thanks so much for your input!
