Optic Armor Oversized Formed Windows Optic Armor oversized formed windows are highly scratch and chemical-resistant while being 50 to 75 percent lighter than glass. They are made from high-optical grade polycarbonate, making them virtually shatterproof, providing added durability as well as safety for the driver or operator. Products requiring a screen printed border are printed with a high-quality, permanent ink that will not flake or crack and gives the window a professional touch. Optic Armor offers many vehicle applications in a formed to factory curvature and their oversized windows allow for a cut-to-fit, flush-to-body install that is not only aerodynamic, but gives the installer the ability to create a custom look. Optic armor windows can be cleaned with standard glass cleaner. Window Type: Rear Window Material: Polycarbonate Trimming Required: Yes Lexan Window Thickness (in.): 0.093 in.
