A few words from pete the ex glass guy...ha!...you knew I couldn't leave this one alone, didn't you! Here's the scoop on broken windshields due to apparent "stress" or otherwise. MOST insurance companies, and I repeat....MOST....don't want to hassle with or get involved with WHAT cracked your Viper windshield. You can simply call them and tell them it's got a long crack in it and that's that. Provided you have the glass coverage and whatever your deductible is, if there is any, you get a new shield put in and go. Windshields generally don't crack due to lack of sealer. Stress cracks have been known to appear in several different makes and models of cars, some of them not even sports cars like the Viper.
IF you want to go back to the dealer for whatever reason, and try to get them to "warranty" the windshield for a stress crack, AND you can prove that nothing else could have cracked it due to the break originating from the very bottom edge, etc, then they might do it under warranty, as several of our club members have done. But, if they don't want to or it's too much trouble, just have your insurance company do it. Hopefully, you have zero deductible on glass, which is often a bit more money but not much. In my humble opinion, worth it. And, the 24-hour set up period your glass installer asked you to provide is not due to the Viper's rigid body, etc. This is the cure time on the urethane sealer that both seals and holds your windshield in and becomes part of the overall rigidity of the car. It actually is driveable long before that, but he wanted to be on the safe side. This is normal. But, obviously, glass shops cannot ask all their customers to "wait" 24 hours before driving off from the shop or after a mobile installation. Pete the ex glass guy and hot rodder with 15 LONG years of installations. Yikes.
