Backglass Perimeter Leaks

A suspected leak in the backglass urethane seal should be confirmed using one of several static test methods. An ultrasonic tester such as J 26419 or Snap-On(R) AC6600 is preferred, but any method that can pinpoint the exact leak location will save time.

Repair Method:
The recommended method for repairing the leak is to flood the leak area with a urethane sealant. Cover the area surrounding the leak sufficiently to avoid creating a new leak path between the leak and the newly applied sealant. Give the sealant sufficient time to cure to avoid blowing a new hole through the sealant.
