It restores the original appearance, weather sealing and occupant protection of the rear opening while matching factory contours and tint.

Installation / Application:
- Difficulty: 3/5
- Estimated time: 1–2 hours (plus adhesive cure time; full cure 24 hours)
Instructions:
- Prepare the vehicle: park on a level surface, disconnect the battery (if required for rear defroster), and protect interior trim with cloths or masking.
- Remove interior trim and any molding that covers the glass perimeter to access the adhesive bead.
- Carefully cut and remove the old glass using a cold knife or windshield cutting tool; remove old urethane from the pinch weld and surrounding flange.
- Clean the pinch weld thoroughly with solvent and allow to dry; apply primer to bare metal areas per adhesive manufacturer instructions.
- Apply a continuous bead of automotive urethane adhesive to the pinch weld using a caulking gun, following the adhesive maker's recommended bead profile.
- Using suction cups, lift and position the new rear window into the opening, aligning contours and flange. Press the glass evenly into the urethane to seat it fully.
- Secure the glass with gentle tape or supports as needed to maintain position during initial cure.
- Allow adhesive to set according to the urethane manufacturer's handling and full-cure times (typically handle in 1–2 hours; full cure ~24 hours).
- Reinstall trim, molding and any electrical connections (rear defroster). Verify proper sealing and inspect for leaks after cure.
- Dispose of broken glass and old adhesive per local regulations. Test drive only after adhesive has reached safe handling strength.
