To install:
  1. Clean ALL traces of urethane from the pinch weld flange. To prevent corrosion, paint damage on the pinch weld by the knife must be covered with primer before installing the window.

  3. Two primers are provided in GM's kit (P/N 9636067). The clear primer is used prior to the black primer. Apply primer around the entire perimeter of the assembly. Allow to dry. Then apply the black primer over the clear primer and to the pinch weld flange. Allow to dry about 5 minutes.

  5. Apply a smooth continuous 3 / 8 in. (10mm) bead of urethane around the window assembly.
