If the second roadtest verified the need to seal the top of the windshield, mask off the top of the windshield encapsulation and the leading edge of
the roof with tape so that only the crevice between the roof and windshield is exposed. This will protect the windshield and painted roof surface
from damage due to contact with the sealer. (See Figure 1)
6.
Obtain locally or from Kem Krest (1-800-955-8591) Permatex Auto Glass Sealer P/N DWS 37 or equivalent, and sparingly apply to the cavity
between the roof and windshield encapsulation, following the directions on the package. Note: This product flows into gaps best at or above
normal room temperature.
Important:
Do not use any sealer which contains silicone.
Be sure it is smooth and evenly distributed along the entire length of the windshield header. Clean off any excess sealant following the package
directions. Remove masking tape and clean off any tape adhesive left behind with adhesive remover.
7.
Test fit the A-pillar weatherstrips (P/N 15715158) to the A-pillar encapsulation (See Figure 1) and clean the areas of contact. Remove the
weatherstrips.
8.
Apply a 1/8th inch thick bead of GM Weatherstrip Adhesive, P/N 12345097 (available from Kern Krest) or equivalent, to the inside crevice of one
A-pillar weatherstrip.
9.
Install and align the weatherstrip to the A-pillar windshield encapsulation then repeat the process for the other side.
