Teak wood

[nipper]

Cetol is called Sikkens Cetol, and it is made by a company (swedish, I think) called Azko Nobel. It is available at any marine store. It runs about $35 a quart, but a quart goes a loooong way. I tend to agree with Fitz about not using it on the hatch covers. However, I have used it on swim platforms which invariably get some nicks and scratches from water skis, etc. When that happens, you can lightly sand the blemish and apply a bit of the cetol and you will never know it happened. Cetol can also produce a somewhat slippery finish. The instructions on the can indicate you can sand lightly between coats with fine sandpaper, but caution against doing so on surfaces subject to foot traffic.
