If you haven't been impressed with Cetol,
it's prob'ly because the owners didn't do a good job of prepping the teak before they applied it. It's as much work to apply the first time as varnish--the wood has to be cleaned VERY well, sanded as smooth as baby's bottom, and absolutely dry. Unfortunately, too many boat owners don't do any more than they did to use oil--throw some two step teak cleaner at the wood and that's all (worse yet, they use a stiff brush, or even a wire brush to clean the teak, which digs the soft wood out of the grain)...and they also try to rush the job...applying it before the wood is completely dry, and slapping on like oil. But when it's done right, it's not "muddy" and looks like a hand rubbed tung oil finish. Or, if you insist on a high gloss, you can put a gloss topcoat on it.It's a major job the first time...the benefits come every season afterward, when all you ever have to do is lightly "sand" with very fine bronze wool and apply another coat. I've used it on my boats for more than 10 years...wouldn't use anything else--with the POSSIBLE exception of Armada.
