In finishing structural wood on aircraft, one must be sure the varnish is UV
and solvent proof (the glues used to attach the fabric to the airframe have
pretty "hot" solvents) and be highly resistant to moisture penetration.  I
had some epoxy spar varnish left over from an aircraft project (which was
impervious to Methyl Ethyl Ketone and probably about everything else short
of gamma radiation) that I used to finish a new wood exterior door at least
3-1/2 years ago.  It faces the afternoon sun here in Texas, and has held up
very well.  It is slightly reticulated (tiny cracks) and a little
oxidized-looking on the surface, but the wood beneath is protected.  You can
buy it from Wicks Aircraft Supply (1-800-221-9425).  The smallest quantity
they sell is a quart at $28.26, and athe catalyst is $11.89 for a pint
(enough, since you mix it 2:1).  It goes on like varnish (probably needs a
little thinning before brushing or spraying), so if you don't like that
thick plastic look, it might be just the ticket for a long-lasting finish.
It has a slight amber color and will add a slight tint as most varnishes
tend to do.
