Does uncoated fiberglass lose it's strength with long term exposure to

Yes, you need to cover it. Fiberglass does degrade with UV
exposure. That's why you cover it.


Sorry Ganz, but fiberglass does NOT degrade because of UV exposure. Glass
is proof against UV. It's not the glass that's the problem. It's the resin
that binds the glass. Perhaps if you had not consumed mass quantities of
illegal drugs you would be able to demonstrate clear thinking once in a
while.

The glass in fiberglass is affected by UV exposure.
