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.
- elil17 3y agoSeems 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.
- heavyset_go 3y agoI feel like if you're really hard pressed for a UV blocker you could just use mud.
- svachalek 3y agoYeah I've seen old boats turn to dust. UV utterly destroys fiberglass given a little time.
