My boat has a pretty considerable amount of teak. About 6 years ago, it was all stripped to bare wood and coated with Cetol. It's been re-coated three time since. It's not in awful shape now, but there are places where it's worn through or is peeling. I think there's nothing to do but sand and scrape it all off and go back to square one.
Once back to bare wood again, what would you do?
Cetol again?
Varnish?
Leave it bare?
I know this is highly subjective, but I'm very interested in people's preferences and reasons.
