Abstract
An apparatus for repairing windshields and the method for using the apparatus wherein a liquid, curable resin material is forced into cracks in the windshield, using an apparatus mounted directly to the windshield, and which provides a high injection pressure and subsequently a vacuum so that the crack is completely filled, and air bubbles are removed from the filling resin during the time the resin cures. The apparatus in one form includes a disposable, simple-to-make injector that seals positively around the opening of the crack so that the resin is forced into place, and by reversing the injector, a suitable vacuum can be applied to the injected resin for removal of air bubbles.
