How do you tint the back glass on a 2011 Mustang convertible?

Answer 1: It’s very difficult to slide the film behind the seal on these models. This means that you will not have enough space to slide it behind, and you will mostly need to use guesswork to come up with a good final result.    Answer 2: Hang a quarter of an inch over the seal. Next, use a straight knife to trim around the edge of the seal. To keep your cuts clean, use a straight tool as a guide. It’s very important to avoid cutting the surface at all costs.    Answer 3: Use a precut kit, and you will not have to worry about any of these issues.
