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 dam and fasteners 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 the old adhesive, the clips, the rubber dam, and the dashboard seal from the windshield with a putty knife. Clean the bonding surfaces on the inside face and the edge of the windshield with isopropyl alcohol. Make sure the bonding surface is kept free of water, oil, and grease.
11. Apply glass primer to the upper clips mounting areas on the windshield (A), and let it dry. Remove the adhesive backing and attach the upper rubber dam (B), lower rubber dam (C), and the upper clips (D) to the inside of the windshield as shown:

- Apply glass primer to the molding.
- Do not apply body primer to the windshield, and do not get body and glass primer sponges mixed up.

- 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.
- Cover on the dashboard before applying the primer.
- Be careful not to mix up the body and glass primer sponges.
- Never touch the primed surfaces with your hands.

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 dams (C) and the molding (D) as shown.
NOTE: 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 made in step 15, and set it down on the adhesive. Lightly push on the windshield until its edges are fully seated on adhesive all the way around.
NOTE: Do not open or close any of 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.
23. Wait at least an hour for the adhesive to dry, then spray water over the windshield and check for leaks. Mark leaking areas, and let the windshield dry, then seal with sealant.
