How to Repair Windshield Pits

While smaller chips in a windshield, known as "pits," may not pose a risk of turning into cracks, they can be dangerous if they obscure your vision. You can repair windshield pits with a special resin-based polymer that fills in pits and is then buffed smooth after it has cured. While some auto parts stores sell supplies separately, it may be easier, and more cost-effective, to purchase a kit. Keep in mind that kits may not all have the same components and you should confirm you have all the necessary items.

Instructions

    1

    Wash and dry the windshield.

    2

    Apply pit resin, one drop at a time, until the pit is filled.

    3

    Place a strip of curing film over the resin and apply the ultraviolet light for three minutes.

    4

    Rest the area for five minutes and test gently with your fingernail. If the resin feels hard, gently remove the film by scraping with a razor blade.

    5

    Remove any excess resin from the top of the repair with the razor blade.

    6

    Attach the buffing wheel to the drill or buffer. Apply a few drops of glass polish to the repaired area and work the buffer over the repair by moving the wheel in short circular motions, while applying light pressure.
