As per an earlier thread, I ended up epoxy coating one decayed wooden
gutter (with multiple coats and some fiberglass) and one undecayed
wooden gutter that I just surface coated with the intention of
preventing future rot.

Now since epoxy is UV sensitive, I assume I need to coat the epoxy
with something to protect it from UV.

What would be the best coating that would stand up to the water-logged
nature of gutters and to sun UV exposure? I am looking for a solution
that requires the least maintenance and repeat coating.

Would you recommend paint? If so what type and is primer required?
What about a poly spar varnish?
Any other suggestions?

Note: after applying the epoxy coating, I noticed someone cautioning
against epoxy (or any other non-breathable) coating of wooden gutters
since trapped moisture can rot the gutter from within if the coating
is impervious. The site recommends instead breathable coatings like
various oils. But I went with the advice on this group (and also the
advice from West Systems tech support) and it's too late...

Stop and think for a minute...automotive finishes stay out in the sun
all day in many places. The autobody supply stores have Bondo
(fabulous stuff), fillers, primers, and the list goes on. A lot of
what you need comes in spray cans if you are compressor and spray gun
deprived. A nice metallic topcoat would reflect a lot of incident UV.
When the sun warms the gutters any trapped moisture will be driven
out. Bottom line, use materials appropriate to the environment. Use
the spar varnish on your yacht.
