Sun Dimmers has the latest Llumar Precision Cut Software and Hardware available for cutting the film to your car’s exact specs. The old risky way is to use a razor blade to cut the film on the outside of your vehicle windows. We will not use a razor on your car! Each LLumar window film pattern is computer-generated and cut precisely to factory specifications in order to ensure a perfect fit every time. There is no harm to your glass and window rubber when we work on your car.
