A windshield is a sheet of safety glass that covers the driver and passenger compartment in a vehicle. Windshields are made from two sheets of glass, with a laminate sheet glued between them. This laminate sheets prevents the glass from shattering if the glass is cracked. A windshield is not indestructible, however, and even a slight nick in it can stretch into a large crack that can be both unsightly and dangerous. You can use super glue to temporarily seal the nick from moisture, which can expand the nick into a crack, if not treated.

Skill level:

Things you need

  • Super glue
  • Tape
  • Flathead screwdriver
  • An assistant (optional)

  1. 1

    Tape up the head of your flathead screwdriver. Use the screwdriver on the inside of the windshield to press the windshield outward.

  2. 2

    Reach inside the vehicle and hold the taped-up head of the flat head screwdriver against the nick in the windshield. Stand outside the vehicle with the super glue ready for use. If you can't reach the nicked area from the inside of the vehicle (or from the outside), ask a friend for help with one of these two tasks.

  3. 3

    Uncap the superglue bottle and press the nozzle to the end point of the nick on the windshield.

  4. 4

    Press the flathead screwdriver against the same point that the super glue bottle is pressing against, but from the inside of the windshield, rather than from the outside. Pressing here opens the nick slightly, allowing glue to flow into the nick. Squeeze the super glue bottle to allow glue to flow into the nick.

  5. 5

    Move the screwdriver and nozzle of the super glue bottle along the nick, from the end point to the starting point, in order to seal the entire nick. Avoid driving the vehicle until the super glue has cured.

Tips and warnings

  • Ensure that the super glue does not dribble out of the nozzle too much; when it dries, it is visible and unsightly.
  • Super glue will seal the crack only temporarily. Be sure to eventually use a repair kit or to ask a professional to repair the crack.
