I like any of the marine versions I've tried and find them pretty similar in quality. The important thing is getting enough coats on at the start. That done, for my climate, it's simply a coat a season to maintain the overall coating.

It will protect the wood on the average, 10 years or so before the coating fails and needs to be removed. Some wooden parts, due to their angles, to the sun may only last 5 years without covers(handrails). Others, like spars, may go 15 years or more. These cabin sides should go 10 years

If you have brightwork in good shape, be sure to maintain it with a coat each year. If you live more southerly, you may need two coats. Talk to people in your area that maintain brightwork.
