Does uncoated fiberglass lose it's strength with long term exposure to
UV light? Should I cover it with paint or gelcoat? This is some wooden
thing I built and coated with cloth and resin. Thanks all,

Yes, Milton, assuming you are talking about either polyester resin or
epoxy resin, neither one is much good against UV radiation. Cover it
with gelcoat. Be sure to add wax for a glossy surface.
