In the state of texas you may apply up to a 30% window film to your front two windows and you can go as dark as you would like on the back half. Adding a window tint eyebrow to the front will make the front two side windows appear darker than normal by not letting as much light in from the front windshield. In Texas you can also apply a clear window film to the front windshield as long as it does not read darker than 70%. Doing this will reject the most heat when using our specialty Madico IR heat rejecting film.
