The CRL Windshield Saver Kit uses a two-part epoxy compound to repair stone-damaged windshields. The compound hardens and bonds to fill chip crevices, preventing radial cracks. The clear epoxy will not affect visibility. There is no drilling required, so application is easy, and it's effective on a wide range of pit types, restoring the windshield to nearly new condition. Single application and five application fleet packs contain everything necessary for a complete repair.
