I was wondering if anyone knows of a window tint film that is safe for use on plastics for sale in the Canada and/or the U.S. ?

I've seen one for sale in England, but I'd prefer not to buy over the net and have to exchange some dollars to British pounds.

I was interested in the films that apply with static, but I've done some research and all the films readily available here are not safe for plastics, acrylic, polycarbonate etc.

Thanks.
