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

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.

16. Push in the injector until the white seal touches the glass, and then push 1 to 2 additional clicks to ensure a proper seal.

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.

19. With slight pressure, use a cork on the inside of the windshield to flex and massage the damaged area to help the resin flow into the break.
    NOTE: Temporarily move the mirror aside as required.

20. Repeat step  17 through step  19 until the last injection sequence is free of air and legs of the chip are filled with resin.
    NOTE: Monitor inside of the seal for air bubbles.

24. Clean excess resin from the impact point.
    NOTE: Do not wipe any suction cup sealant into the unfinished pit.
25. Apply one drop of Pit Filler just above the impact point, and then place a clean dry film tab over the filler.
    NOTE: Do not press down on the film tab.

26. Position the curing light over the film tab for 1 minute.
    NOTE: Ensure no air is present beneath the film tab. The resin requires anaerobic curing.
