That's covered most of the time so doesn't really count. The coating is so thick, it's hard to believe. A guy that works professionally doing varnish here in town, had a business down south doing the same for a few years. He liked to see his customers come twice a year to keep up with maintenance. Here, that's mostly annual.

Up here, he pointed out a boat, with bright cabin and coamings, etc, that had gone at least 25 years with nothing being wooded. It looked it, darkened and thickly coated with voids that had been repaired. He said of course it should be wooded. If you keep after it, it will last quite a while. Afterall, it is just a coating, it will last longer if it's continually recoated.

I get an average of about 8 years with the variations being how the piece is oriented to the sun. While people think they're the most labor intensive, spars are not and can go 2 decades or more with just a yearly coat. Some around here coat their spars every other year.

If I was smart, I would have a few covers made for the most sun beaten pieces for my boat. Some day;;;

This is the boat that most amazes me. A working boat spending summers in Maine doing several tours a day with heavy people traffic. It heads to the Caribbean for the winter doing the same work. It rarely takes a break except for an annual haul of a week or two.

The husband and wife are professionals in the boat building business. She does all the brightwork and says she adds another coating in the Caribbean on a few high traffic/sun baked areas, and that's it. Plus they home school and raise two kids as they live onboard in the winters.
