  • Patent number: 6634695
    Abstract: A means and method for protecting a windshield from damage and therefore the development of cracks due to stone or other impact on windshields around the peripheral area. An impact resistant barrier is placed around the periphery of the windshield. The barrier is preferably a clear polymeric film, but could be opaque, rubber, plastic or metal. The barrier is placed on the glass surface and in contact adjacent to the windshield molding. The width of the barrier is selected to eliminate the higher incidence of damage to the peripheral area. The barrier can be combined with a sunlight blocking ingredient to reduce degeneration of urethane which is used in mounting the windshield to the vehicle. A kit can be assembled with the elements needed to place the barrier on a windshield. The barrier can be applied in fluid form which achieves a film. The barrier can extend not only over the front surface, but also over the edge surface and the back surface.
