Yesterday I was visiting with a friend about some old cars in general and this came into the conversation. Feel free to add comments.
I had bought some cars and am still dealing on others from a local ranch. Last summer a bad hailstorm came through there. The 63 Fairlane coupe I bought got it pretty bad. The 38 Ford I bought sitting next to it didn't show much damaged except to the aluminum visor. Same with the 49 Fleetline but the trim was pretty banged up on it. Guide headlights on an old Diamond T were pretty banged up but the rest of the truck showed no damage. 51 GMC 3500-no visible damage. But the 36 chevy coupe is totally beat to crap. It looks 10 times worse than any of the others, even has the windshield broke out. All of the cars were setting randomly around an small area. There were also some 60s GM cars and they don't show the heavy damage.
About 1/2 a mile away are more cars and parked in some random pine trees, various damage but again, the 36 Chevy pickup took it the worst and is again the only one that got windows broke out. There were several other 30s and 40s Fords there and some 60s GM cars too.
Conclusion: 36 Chevys are very soft metal and weak glass.
