For over 20 years manufactures have been producing cars with composite headlamp units made from either polycarbonate or acrylic materials. While these materials are great for the design aspect, they have a reputation for being less durable than glass and having a tendency to deteriorate over time. Polycarbonate lenses can become cloudy and discolored due to oxidation caused by UV rays. While sanding or polishing the surface can buy you some time, this process actually removes the hard coat on the lens accelerating the wear and tear. The most common issue with composite headlights is the sandblasting caused by rocks, road salt, debris, and sand. This pitting and cracking not only affects the appearance, but also seriously degrades the performance of your lights. By installing Headlight Protection Film to your lights, your will be able to maintain your original headlight condition and save yourself hundreds of dollars. Shadow Shield distributes high quality headlight films that range from clear film to numerous colored films for customizing your vehicle.
