How to Repair a Windshield Spider Crack

How to Repair a Windshield Spider Crack

Repairing a windshield used to mean making an appointment to take the car in to the dealership, getting an estimate, approving the quote, waiting again for the repairs to begin and finally paying a large bill for labor, service and parts. Now, there are several types of windshield repair kits that are easy to use without the assistance of a professional mechanic. These kits can be found in most auto parts stores. Each kit also comes with a set of easy-to-follow directions.

Instructions

    1

    Remove any glass fragments left in the crack with the razor blade supplied in the kit. Scrape over every line crack to ensure no glass remains. Wash the windshield with water and wipe it off with a paper towel.

    2

    Remove the suction cups from the windshield repair kit and place them over the crack. The center area between the cups should be just above the spider crack. Press the four suction cups onto the windshield to affix them in place.

    3

    Screw the supplied repair tube into the center of the suction cup apparatus. Continue to screw the tube until it is firmly against the center of the crack. Sit inside of the car to get a clear view of the tube. Ensure the tube is in the center of the crack. Reposition the tube as necessary.

    4

    Remove the center screw of the repair tube by unscrewing it. The open end of the repair tube will remain in place on top of the crack. Remove the top of the provided repair resin and slowly drip five to six drops into the center of the fixed repair tube.

    5

    Reinsert the center screw into the repair tube and tighten it until it touches the windshield. Tighten the screw more to force the resin into the crack. Unscrew it briefly to remove any trapped air then retighten the screw to the windshield. Keep the screw tightly in place for at least two minutes.

    6

    Unscrew the fixed repair tube and place a sheet of the provided plexiglass over the wet resin. Firmly press the plexiglass against the windshield. Firmly scrape the plexiglass over the lines and the crack it covers with the razor blade. Wait for the plexiglass and resin to set for at least one to two hours.

    7

    Peel the plexiglass strip gently away from the crack. Scrape any remaining plexiglass away with the razor blade. The crack should now be filled.
