Repair Kit

  1. Move your car to a shady area. The sun can dry the adhesive chip too fast.
  2. Completely dry the windshield clean fluffy towels. When water enters a crack, it moves quickly and acts as abrasive. This moisture can spread cracks and needs to be removed before performing a repair.
  3. Apply one of the adhesive strips centered on the chip kit windshield. Attach the device on this strip with the cylinder pointing up.
  4. Remove the cap from the syringe provided and put the tip into the opening of the appliance. It is full of adhesive used to fill the chip. Pull the handle of the syringe up and leave at the peak for a minute. This brings any crack and bubble adhesive prepared for injection.
  5. Release the handle of the syringe, allowing the adhesive to be pushed into the crack. Repeat this process until a suitable amount of adhesive has been inserted.
  6. Removes the syringe, the device and the windshield adhesive strip. A small bump should be visible above the crack. Let dry for an hour before removing it with a razor blade. Use a towel soaked in alcohol to remove any remaining adhesive out of the crack.
