Too hard for me to test in my basement "laboratory." The assumption that it was involved, though, is the reason I kept my suit sealed in an airtight container when not in use.
EDIT: I forgot to add this.
I was told that ozone damage results in a form of dry rot, with the seal drying out and falling apart. The degradation I was seeing was a sticky, gooey mess, with the latex turning into something that looked like tar. Do a search and you will find past threads on this. It happened all over the world.
Ah -- mine failed with cracking and checkering in places.
