Re: Minwax Helmsman Spar Urethane instead of paint?
Yacht "brightwork" would typically have about five to seven coats applied to completely fill the grain. Well maintained boats would have a minimum of one coat applied each year. Some boats received a coat of varnish at the end of the season as well, but that is rare from my experience.
It will require constant spotting and re coating to maintain the look you're hoping for.
