I used Interlux 60 satin finish varnish. Two coats. Removed every piece of teak that would come off and did it in a protected area of our basement. Tackled the job in stages I.e. Galley, head, quarter berth so I didn't get frustrated and try to rush the job. Great outcome. Used cetol on the exterior, I thought it was a bit too translucent to let all the beautiful grain show through for the interior work, also a bit orange...
