anyone with teak spray rails...

[Bushwacker]

I've used Honey Teak, which was the most durable product a few years ago. It leaves a fairly dark finish. A more durable product tested a couple of years later by PowerBoat Reports is Epifanes Wood Gloss. I've used it on a teak handrail and the side boards in the cockpit of my Seafari. It's a lighter finish and does appear to be more durable than the Honey Teak if you apply the recommended 5-6 coats. All of the varnishes are more durable than the teak oils, which oxidize and turn very dark in S. Fla. in only a few months. I used the oils for years but got tired of the maintenance. The varnish is MUCH more durable, especially if you keep a cover on the boat.

This is a shot of cabin door done with Honey Teak. The hand rail and wheel hub were done with Epifanes.
The cockpit side boards in this shot were done with Epifanes.
