Traditionally auto manufacturers have been producing cars with composite headlamp units made from either polycarbonate or acrylic materials. While these elements are great for the design aspect, they have a tendency to deteriorate over time. Polycarbonate lenses can become cloudy and discolored due to oxidation caused by harmful UV rays, and become pitted by rocks, road salt, debris and sand. This pitting and cracking not only affects the appearance, but it also reduces the performance of your lights. XPEL film is designed to protect from all of these elements. In fact, it can actually help restore lights that are showing signs of wear from pitting. Acting like a wax, the adhesive fills in the surface defects, creating a shiny consistent surface while protecting from any further damage. XPEL Headlamp Protection Film is a patented, 30 mil (.030 inch) thick, high performance self adhesive PVC film with a scratch resistant polyurethane coating, designed to protect glass and polycarbonate lighting surfaces from the harmful effects of stone chips, abrasion and weathering. This film is exceptionally conformable when heated for ease of application over the most complex contours. XPEL Headlamp Protection Film is non-yellowing and offers environmental resistance as well as superior gloss retention and optical clarity. XPEL Headlamp Protection Film is laminated with a 3M high performance acrylic adhesive which has excellent adhesion on a broad range of surfaces.
