Thanks for the reply. I realize it's illegal in the US, I was hoping someone may have done it anyway and had some experience to share.
Unfortunately the non-metallized films like Crystalline are extremely expensive here, US$700-800, while the lower-end tints such as the FX HP are a quarter of that price.
