Choices
Steve,As with all things on a boat, the answer to your question is, "It depends." As I see it, you really have three choices: Teak oil - depending on the intensity of the sun where you are, oiling your teak will last anywhere from 2 - 4 months and then you have to do it again. Best to mask off the surrounding fiberglass as teak oil can stain it. Cetol (or similar product) - if applied according to the directions, Cetol will last a year. Some folks don't like the color, but different strokes . . . Varnish - this is the traditional finish and probably the most time intensive of your choices. A good surface properly prepared with a thinned out first coat and then successive coats will last a long time and look very professional. I have one exposed strip of teak on my H380 (companionway hatch) and I put 8 coats of varnish on it. It is ready for another coat or two, but I do like how it looks.Hope this helps.Fair winds,SteveS/V Options
