I have two roadsters. One has always been garaged, it has its original top. The other spent the first 10 years of its life mostly garaged. We bought that car in 2015 and it has spent much of the time since then parked outdoors in the shade. The glass fell out in 2017 and we replaced the top. The car with the new top has spent its life in AZ, The car with the original top spent the first half of its life in WA and the rest in AZ.
I spoke too soon, the window is coming loose on my black roadster. At least I’m experienced!
