Does the tint go on the inside or the outside of the windows?

Window tint will be installed on the inside of the car. The tint does go on the inside of the glass so it is protected against the elements. You will see the installers at Extreme Autoworks molding the tint on the outside of the vehicle, and that is so the tint can take the shape of the glass. Every car window will have a natural curve or bow to it and the tint needs to take the same shape to ensure a clean and correct install.
