McKee's 37 Graphene Headlight Coating is a nano-glass graphene ceramic coating designed specifically for polycarbonate headlight and taillight lenses. This high-solids formula adds an extra film of clear coat over new or restored headlight lenses, leaving them crystal clear and well-protected for up to 3 years. Designed to prevent UV-induced fading and discoloring, applying McKee's 37 Graphene Headlight Coating to a brand-new vehicle will save you hundreds, if not thousands of dollars, over the course of ownership of the vehicle by preventing costly headlights from deteriorating.
