Good points! Their site also states a lot of things the buyer shouldn't do with this product on their car.Invisible Windshield Protection Films by ClearPlex®
There isn't much on their site as to their warranty. Doesn't look like a ton of retailers carry it or offer it yet either. I also wonder about the extra wear it would cause windshield wipers and the extra resistance between the blade and glass causing the wiper motor to prematurely wear out.
Good product so far, just lots of questions as to it's usability.
