A small chip in a car's windscreen, or windshield, can turn into a large crack easily, which will ultimately require you to replace the windscreen. Fortunately, windscreen repair kits are available at most auto parts stores. These kits typically feature all the materials necessary to repair the chip.

  1. 1

    Clean the area around the chip with glass cleaner and a paper towel, or use the cleaning wipes if they were supplied with your kit. Let the area dry completely.

  2. 2

    Punch out the hole in the centre of the adhesive disc that came with the kit. Peel off the adhesive backing facing the glass and place the hole directly over the chip.

  3. 3

    Remove the adhesive on the side facing outward. Place the pedestal that came with the kit on top of the adhesive disc.

  4. 4

    Insert the syringe into the pedestal. Make sure that it sits firmly within the pedestal.

  5. 5

    Use steady pressure to pull the plunger from the syringe to suck any air out of the chip. Push the plunger back down slowly and evenly to fill the chip with the epoxy. Repeat 10 times.

  6. 6

    Allow the epoxy to dry for 30 minutes. Leave the syringe in the pedestal while you wait.

  7. 7

    Remove the syringe and cut the pedestal away from the glass with a razor blade along with the adhesive disc. Clean the area again with glass cleaner or the supplied wipes.
