WINDSHIELD PERIMETER LEAK
A suspected leak in the windshield urethane seal should be confirmed in the shop using one of the several static test methods. An ultrasonic tester such as
Kent Moore J26419 or Snap-On AC6600 is preferred, but any method, that can pinpoint the exact leak location, will save valuable time.
Repair Method:
The recommended procedure for repairing the leak path is to remove the moldings as necessary and flood the leak path with urethane sealant. (See figure
for example). Cover the area surrounding the leak sufficiently to avoid creating a new leak path between the leak and the newly applied sealant. Give the
new sealant sufficient time to cure as to avoid blowing a new hole through the sealant.
