INSTALLATION

CAUTION: After installing a new urethane-installed glass, the vehicle should not be driven until the urethane sealant has cured. The curing times at temperatures above 13°C (55°F) and relative humidity above 50 % is 12-24 hours (decreasing at higher temperatures and lower humidities). Inadequate curing of the urethane sealant may adversely affect the strength of the urethane sealant bond.

1. Dry fit the back window glass. Make alignment makes with tape or non-staining grease pencil.







2. Trim the remaining urethane sealant on the pinch weld to within specification.

CAUTION: Avoid scratching the pinch weld area.

3. Use a wool applicator to apply Urethane Metal Primer Essex U-413 meeting Ford specification WSB-M2G234-C to any exposed metal on the pinch weld. Allow six to ten minutes to dry.
4. If reinstalling the original back window glass, remove the excess urethane sealant from the back window glass.
5. If a new back window glass is to be installed, attach the new molding to the edge of the glass starting at the top center, then working out, then down pillars and around the corners.

7. Apply Urethane Glass Prep Essex U-401 meeting Ford specification WSB-M2G314-B twice around the surface to be urethaned.
