UV from sunlight degrades fiberglass/FRP over time. I believe that boats are painted to protect them from this, and need to be recoated periodically because the uv sunlight will degrade the paint eventually, also.

Seems unlikely that you’d have a reliable source of paint for 1000 years, which might be the limiting factor.

But there’s always some rate of chain scission, even in the absence of UV/water/whatever. I just have no idea whether that has a meaningful impact on material properties over 1000 years.

I feel like if you're really hard pressed for a UV blocker you could just use mud.

Yeah I've seen old boats turn to dust. UV utterly destroys fiberglass given a little time.
