If you are looking for the ultimate in high technology, superior clarity and performance with a premium look – Then Ameraguard Ceramic Automotive Window Film is for you. Ameraguard Ceramic Automotive Window Films feature a proprietary, multilayer optical film technology that combines over 200 layers in a film that is thinner than a Post-it® Note. This unique technology is the reason a clear film can reject more heat than darker films, without changing your car’s appearance.
