I LOVE teak on a boat and I think its a shame the new production boats have so little of it.
I did my Grady with Epifanes and Cetol. The Epifanes was used in the helm area which is not as exposed to the elements as the cockpit, where I used Cetol. Cetol is tougher and better able to withstand the abuse from the elements then regular varnish, but the regular varnish is beautiful.
The Epifanes is excellent. As Busheacker said, thin the first coat 50%, follwed by 30%, 15% and 10%. This builds a nice base for the topcoats which are applied at fullstrength. In between the fullstrength coats I even sand with 220 grit, but only ever so lightly. I normally do the 4 base coats and 4-5 top coats, sanding with 320 between the last coat.
The cetol is simpler and easier. Apply the 3 coats of base at fullstrength follwed by 3 coats of gloss with light sanding between coats.
Joey did what I consider the ULTIMATE teak finish. Epoxy followed by Clear Awlgrip or Imron. If it lasts 12 months in the direct Florida sun, it will last a easy 5-6 years up here.
My next year plan is to coat the varnish on my boat with clear imron. Although I didn't treat it with epoxy from my understanding the multiple coats of varnish can be overcoated with Imron as they already built a base and filled the grain.
