Wood finish choice is nearly as controversial as anchors. I have some Cetol areas, it works and lasts well enough and application is easy, but for rails etc I use Deks Olje 1 & 2 to produce a finish inferior to Cetol or varnish but way easier to maintain and recoat. In 10 years I`ve not had to go back to bare wood.
Where I felt I had to reduce the amount of material I was removing I have used a teak color stain to revive the teak color without hard sanding.
Thanks, Bruce and all. You may be right about some two-part Finish underneath. since my original post, I found a local guy who specializes in refinishing boats. Going to try to have him look it over.
