8. Scrape smooth the old adhesive with a knife until there is a thickness of about 2 mm (0.08 in) on the bonding surface around the entire windshield opening flange:

- Do not scrape down to the painted surface of the body; damaged paint will interfere with proper bonding.
- Remove the rubber dams and the clips from the body.

9. Clean the body bonding surface with a shop towel dampened in isopropyl alcohol. After cleaning, keep oil, grease and water from getting on the clean surface.

10. If you are reinstalling the old windshield, scrape off all of the old adhesive, the clips and the rubber dams from the windshield with a putty knife.

Be careful not to touch the windshield where the adhesive will be applied.





16. Remove the windshield.

17. Apply a light coat of glass primer to the windshield (A) along the edge of the rubber dams (B) and the windshield molding (C) as shown, then lightly wipe it off with gauze or cheesecloth:

- Apply glass primer to the molding.
- Do not apply body primer to the windshield, and do not mix up the body primer applicator and the glass primer applicator.

- Keep water, dust, and abrasive materials away from primed surfaces.





18. Carefully apply a light coat of body primer to any exposed paint or metal around the flange where new adhesive will be applied. Let the primer dry for at least 10 minutes:

- Do not apply body primer to any remaining original adhesive on the flange.
- Be careful not to mix up the body primer applicator and the glass primer applicator.
- Never touch the primed surfaces with your hands.
- Cover on the dashboard before applying the primer.





19. Cut a "V" in the end of the nozzle (A) on the adhesive cartridge as shown.






20. Put the cartridge in a caulking gun, and run a continuous bead of the adhesive (A) around the edge of the windshield (B) between the rubber dams (C) and the windshield molding (D) as shown. Apply the adhesive within 30 minutes after applying the glass primer. Make a slightly thicker bead at each corner.





21. Hold the windshield with suction cups over the opening, align it with the alignment marks you made in step 15, and set it down on the adhesive. Lightly push on the windshield until its edges are fully seated on the adhesive all the way around.

NOTE: Do not open or close the doors for about an hour until the adhesive is dry.

22. Remove the excess adhesive with a putty knife or a shop towel dampened with isopropyl alcohol.
