SERVICE INFORMATION
When a windshield is being installed in a 2004 - 2010 QX56 the glass primer has to dry (properly flash) for at least three (3) minutes. If the primer is misapplied and touches the PVC carrier of the windshield molding AND is not properly flashed the molding can become bonded to the glass. With this condition and during extreme temperatures the molding expands and contracts resulting in "spalling" (etching/peeling away of glass layers). This can result in windshield cracks over time refer to illustration below.
With any windshield installation, be sure to inform the windshield installer to:
^ Apply the primer in the correct areas only as shown above.
AND
^ Allow the Primer to properly flash for at least three (3) minutes before the windshield molding is installed and comes in contact with the primer.
Example of areas to be primered as shown above. Make sure to allow primer to flash for at least 3 minutes.
