3. WARNING: Repair any corrosion found on the pinch weld. The pinch weld is a structural component of the vehicle. Corrosion left
unrepaired may reduce the structural integrity of the vehicle. Failure to follow this instruction may result in serious injury to vehicle
occupant(s).
NOTE: Avoid scratching the pinch weld. For minor scratches or exposed metal on the pinch weld, see the manufacturer's recommendations.
Using an appropriate tool, trim the urethane adhesive leaving a 1-2 mm (0.04-0.08 in) base of original equipment urethane on the pinch weld.
4. If reinstalling the original rear glass, remove any excess urethane adhesive from the glass.
5. If installing a new rear glass, clean the inside of the glass surface with glass cleaner.
6. NOTE:
-
Be sure to use the same brand and cure-rate products for the adhesive and primer. Do not mix different brands of urethane and primer.
-
Sika uses the same black primer for the glass and pinchweld area.
If installing a new rear glass, apply urethane glass primer according to manufacturer's instructions. Allow at least 6 minutes to dry.
7. Cut the applicator tip to specification.
8. NOTE: Use either a high-ratio, electric or battery-operated caulk gun that applies the urethane with less effort and a continuous bead.
Apply a bead of urethane adhesive on top of the existing trimmed urethane adhesive bead on the pinch weld. Make sure that all gaps in the
urethane adhesive are smoothed into one continuous bead starting and ending at the bottom of the rear glass near the center.
9. CAUTION: Open a window to prevent the rear glass from being pushed out by air pressure when a door is closed.
