  1. With a knife, scrape the old adhesive smooth to a thickness of about 2 mm (0.08 in.) on the bonding surface around the entire rear window glass opening flange :
    1. Do not scrape down to the painted surface of the body; damaged paint will interfere with proper bonding.
    2. Remove the rubber dam and fasteners from the body.
    3. Mask off surrounding surfaces before painting.

  3. With a sponge, apply a light coat of body primer to the original adhesive remaining around the windshield opening flange. Let the body primer dry for at least 10 minutes.
    1. Do not apply glass primer to the body, and be careful not to mix up glass and body primer sponges.
    2. Never touch the primed surfaces with your hands.
    3. Mask off the dashboard before painting the flange.

  4. Apply a light coat of glass primer to the outside of the fasteners.
    1. Never touch the primed surface with your hand. If you do, the adhesive may not bond to the glass properly, causing a leak after the tailgate glass is installed.
    2. Do not apply body primer to the glass.
    3. Keep water, dust, and abrasive materials away from the primer.
