Patent ID: 7125507

Claim:
A method of repairing a long sharply turning crack in a windshield comprising the steps of: providing a crack repair tool having an elongate frame having a central portion having three suction cup; each having an upright axis, and each oriented for attachment to the windshield; an injection head on one end, substantially spaced along the frame from the central portion having the three suction cups; and, an upright frame height adjustment means on the other opposite end; lubricating the suction heads to facilitate attachment to and movement along the crack; positioning the tool so that the injection head is seated on and above the crack and the suction cups are all seated to a same side of the crack on the windshield, thereby providing substantial space between the turning crack and the injection heads; and, moving the injection head and tool along the crack; whereby the three suction heads act in concert to provide sufficient stability to the injection head even when spaced substantially therefrom, said substantial space safely accommodating sharp turns in the crack without the risk of ruining the windshield by passing the lubricated cups over the uninjected crack.
