I applied Semco Teak Sealer last fall (September 2002). It held up very well. I used their "Gold Tone" but like Cetol,it was too orange for my taste.

As a result, I switched to the "Natural" shade this year. Teak looks like fresh-cut teak wood after an application (two coats) of Semnco Natural shade Teak Sealer. The product holds up well and can be scrubbed with soap and water. Additional coats can be applied later without stripping. I used teak oil for years on various boats including my father's 35 foot wood deck cutter, which we completely stripped and reoiled every year or two. We used a variety of teak oils, and tung oil.

Semco used to make the best teak oil, and now, in my opinion, they make the best sealer. West Marine carried it, or you can go the the Semco page on the web.

I bought my quart of Semco at West Marine. It covers well, and a quart will last you a long time.

One cautionary note. however: Don't spill it on your painted or gelcoat surfaces. Apply carefully with a small brush. It soaks into the wood, but the excess runs off easily, so don't apply enough to create excess.

I found that the Goldtone Semco Sealer stained old oxydized gelcoat if I allowed it to run. Mineral spirits did not remove it. I had to use Ajax, and it came off fairly easily with that cleansing powder, but it was a lot of work.

I had no trouble re-sealing my coamings with the natural tone, with no spills, and without stainling the surrounding gelcoat. You apply two coats in one day and that is it. If you neglect your Semco Teak Sealer, Semco makes a two part stripper for the hard jobs. I originally used their stripper to completely strip my untreated but lichen-encrusted coamings last fall,and the stripper works as indicated with no side effects to boat or wood.
