I know a lot of folks denounce the stuff, but I can say now from experience, that it is, in my opinion, pretty damn cool. I refinished my mainsheet blocks exactly one year ago, and they’ve been out in the sun, rain, hail, cold, heat and more sun… and look as nice and shiny as the day I put on the last coat of clear. The varnishes I’ve tried do not begin to fare as well. Skye’s mast, also Cetol’ed, is equally nice after 12 months.
