: How does it deteriorate?

: How much damage is done and strength lost?

: Under what conditions will it deteriorate more or less?

Hi Rehd,

These are my experiences where I use to work. We had rolls of fiber glass that was probably 20 years old that we would use now and then. Also I had a quart of epoxy that set around in my pole barn for years in winter and summer that I would use now and then and it worked OK. But this wasn't clear epoxy so I don't know if clearity would be affected.
