Default Re: Chronic Windshield Cracking---96 Super Stock Camaro

Rusty,
As a racer and auto glass shop owner/operator for 30 + years, here are my suggestions.


The windshield will flex some with the body of the car, more than you may think. It should not break.

Remove the broken windshield and look for a tight spot(s),any place that the windshield(or molding that goes around it) is tight to the body or trim.

Look to see if that the amount of urethane sealant that is around the windshield is got some depth to it. You don't want to have the urethane thin, or squezed out , as the windshield will be almost resting on the metal and the chances of a stress crack greatly increase.

There are some urethanes that are more rigid than others, i would suggest using a less rigid one and make sure that when you install the new windshield that it doesn't get pushed to far into the sealant. The factories use differant methods to keep the windshield from being pushed to far into the urethane. The most common one is to use foam tape 1/4 - 5/16 thick to keep the windshield at the correct hight.The windshield in your car has a three sided molding and the top side of the molding should keep the hight of the top of the windshield correct, but the lower section of the windshield could get pushed in to low, so use some foam on the bottom and sides.

Hope that helps, Dave Casey, 413 734 5277 days at my shop if you have any questions
