Chip Repair Procedure

  1. Inspect the windshield for repair eligibility. See Windshield And Roof Glass Repair And Replacement Guidelines .
  2. Open the LH and RH front doors.
  3. Lower the LH and RH front windows.
  4. Use IPA wipes to clean the windshield thoroughly.
  5. Inspect the glass crack repair kit, ensure all tools are present and resin residue is not present, and then inspect the seals for cracks, wear or swelling.

    Tip: Use of the following tool(s) is recommended:

    • Glass crack repair kit

  8. Apply one drop of suction sealant on each mounting stand suction cup, and then spread the sealant on each cup.
    NOTE: The suction sealant will allow the stand to adhere to the glass and be adjustable for alignment.

  9. Install the mounting stand over the damaged area with the lower leg in the 6 o'clock position.
    NOTE: The 6 o'clock position allows excess suction sealant to flow downwards avoiding the chip during adjustment. Align the stand injector bracket with the chip.

  10. Prepare the resin injector as follows:
    1. Remove the white seal from the tip.
    2. With the injector piston turned fully clockwise, back the piston down by turning counter clockwise until there is approximately 1/2 inch space between the end of the injector and the piston.

  13. Turn the resin injector piston clockwise until the resin appears just above the bottom of the white seal.
    NOTE: Verify the piston is positioned correctly. The resin must not flow out of the injector when turned over.

  14. Install the injector on the mounting stand as follows:
    1. Align the injector teeth with the release lever.
    2. Press down until the white seal almost touches the glass.
    3. Do not install the injector on the glass at this time.

  15. Align the mounting stand and injector with the chip.
    NOTE: Use the mirror reflection to confirm the impact location.

  17. Stabilize the injector with one hand, and then turn the piston counter clockwise until the piston stops to remove the air from the injector.
    NOTE: Hold this initial vacuum stage for 1 to 2 minutes.

  18. Stabilize the injector with one hand, and then turn the piston clockwise until the white seal swells to inject the resin.
    NOTE: Allow the resin to flow for 1 to 2 minutes.
