Abstract
A product and method of restoring a defaced or scratched window using a polyurethane film applied prior or subsequent to the damage to the window. The polyurethane fills in the scratches to the window and restores optical clarity. The polyurethane may be an aliphatic polyester polyurethane or aliphatic acrylic polyurethane. A further method is described which provides a protective coating to a window including a polyurethane film applied before the window is defaced. The film may be removed and reapplied easily to provide restored optical clarity.
