Wow, THANK YOU for this detailed explanation! I appreciate your time.Yeah, I know - been mandated since sometime in the 30s. That's the era I noticed it in antique cars.
I've been in the auto industry for 5 decades and into classics and antiques.
I've also been involved in the butyl vs. urethane thing for classic cars.
If you'd seen my other posts and links to demonstrations of GG windshields, you'd see where I am coming from.
I don't give a rip what MOPAR says because if the GG layer is facing occupants, then the outer layer facing the bugs and rain is not GG. It's still going to chip and get sandblasted and be all sparkly after a few years.
Only one of the two layers of glass is GG - the one in the cabin, the other on the outside is soda lime glass.
The middle binding layer, the flexible layer, remains the same stuff.
People are buying this and assuming a warranty means it's chip proof and crack proof.
No way! It's less likely to suffer a a crack that means replacement, it's less likely to spiderweb, and it won't throw shards of glass in your face with a major impact............ but........
Even Corning says "two times more resistant" - not impervious, not that it will not crack, not that it will not chip, but it's more resistant.
That means it will resist certain impacts or certain types of impacts, and may resist cracking where an ordinary windshield would more easily crack.
But no one has said that it won't crack.
Out of 10 hits, where an ordinary windshield would crack 6 times out of those 10, GG would only crack 3 of those times, just for example.
When someone says their GG windshield chipped or cracked, they need to consider that it did NOT chip or crack other times when ordinary windshields would have cracked. In that time they'd have replaced 2 ordinary windshields and not just 1.
It reduces the chances of damage. If you get hit, you have a better chance, but it's still gonna crack and chip. The biggest thing is that these windshields take that rock almost directly at a 90, it's not a glancing blow.
So there's a great chance that when they say a windshield is two times more resistant, they are referring to a Compass, Mustang, etc.
