From what I've studied (but have limited pracice), the key for
exterior finishes is UV protection. UV damages the wood fibers over
time, resulting in poor adhesion. So you want an exterior finish with
UV inhibitors in them.
After that, your finish should be relatively flexible, to accomodate
the shrink/swell cycles from humidity and heat/cold.
I have a Fine Woodworking article (May/June 2009) that tried various
finishes and recommends Smith & Co Penetrating Epoxy Sealer, followed
by Epiphanes varnish. Or just use the varnish. Either way, you use a
lot of coats.

Here's a version of Epiphanes with phenolic resins and tung oil.
Thank you kindly, Sir.
I will give it a try.

Epiphanes is the choice of the "woodie" crowd at almost any marina.
After 6-8 coats, you will have a decent base. <GRIN>
BTW, 3-4 base coats of laminating epoxy sanded between coats provides
a great base but no UV protection which is why the Epiphanes overcoat.

Pshaw!! I don't want it to look like a bar top. ;-)

No problem, just figure a redo every 2nd-3rd year depending on amount
of sun.

Wow, I have to try some of that. It has the same ingredients as
Waterlox, but it costs half the price.

2nd - 3rd year?? The stuff (McCloskey Spar varnish) that's on there is
about 6 years old and not so bad it couldn't go another year.
I was looking for something that would last a little longer. ;-)

You've set the bar rather low if McCloskey Spar Varnish is almost
adequate. >GRIN>

Wellll, that's why I was askin' about a better product.
SWMBO says I did the McCloskey job in spring of 2003. (She say it was just
before we went to Michigan that year)
But here's the door now:

Appears to have weathered rather well.
If you're lookimg for something better, then after an epoxy base with
an Epiphanes top coat, it's all down hill.
Have fun.
