i dont not agree with checking at the tint shop when you go to get it done. check with your state inspection stations, they have the correct and most up to date laws on what will pass or fail. i live in ma, and i went to get my windows tinted after i asked an inspector. the tint shop said 50% all the way around is the darkest i can go. but the inspector told me 35% so i told them to do the 35% anyways and then went a few months later to get my car inspected and it did pass. just a heads up, so check with your state inspectors.
