There are many options. First of all, you need to know your local tint law. In the US, we have (50) different state tint laws, so always check them out first by creating a search for “State Tint Law” and put in your state, for example CA, WA, NY, FL or TX for Texas. In Texas the following will show you the law: https://www.dps.texas.gov/rsd/vi/consumerinfo/windowTint.htm. Which states many items such as: Sunscreening devices must be applied above the AS-1 line. If there is no AS-1 line, sunscreening devices must end five inches below the top of the windshield. The AS-1 line is important which is about five inches from the top of windshield. Clear UV films are allowed in Texas too. A safety film is UV and has about 85% to 90% Visible Light Transmittance (VLT). There are also Ceramic 85, Ceramic 80, Ceramic 70, Ceramic 50, Lux 70 & Charcoal 70 that some tinters use around the world that have very light VLT’s. The ceramics reject much more heat. Again, always check your local state law and tint what is legal.
