J-B Weld Windshield Saver is a patented windshield repair system that allows for the DIY repair of damage such as "bullseye", "star", and "stone chips" of up to 1 1/4" diameter. The single component resin, along with the pressure lock controlled pedestal and syringe system, allows for the evacuation of existing air in the windshield cracks and penetration of the resin to fill the voids with a clear, sun-activated, fast curing acyrlic resin.
