WINDSHIELD UPPER REVEAL MOLDING GAPPING
High levels of windshield rush can be pinpointed to the upper reveal molding through a simple inspection. If any level of gapping is evident between the
rear sealing lip and the roof, a wind rush condition will exist (See figure). To confirm the extent of the problem, completely cover the entire molding
from front pillar to front pillar with 2" duct tape and road test. The result on a problem car will be a much lower background wind rush level.
Repair Method:
Minor gaps can be closed using any sealing material that will bond to the sealing lip and the roof's painted surface, without damaging either surface.
Clear, double-sided adhesive tape such as Scotch ATG Adhesive Transfer Tape, Number 969, Part 06493 or equivalent works well. Do not use quick set
super glue, as it will react with both the polyvinylchloride (PVC) sealing lip and the body paint and cause more serious repairs.
If the gapping condition is extreme, replace the upper reveal molding. Road test to assure the condition is repaired.
