Michael,
I have not had good luck with Marine Spar Varnish on my WA5VJB cheap yagis. Even if you use high quality spar varnish, it is damaged with the constant exposure to sunlight. Signs of damage were apparent after one year and almost total loss after the second year. My antennas were exposed to the NY weather which I would think is not as bad as yours with regard to the sunlight.
My portable satellite station uses varnish coated WA5VJB antennas, but they spend most of their time stored in my garage or otherwise protected from the elements. They are better than 5 years old and still have a nice gloss finish.
I am trying high quality exterior house paint this time
