Bill, that is a wonderful piece of work. I love the suspended seat. I would respectfully disagree with your planned finish however. I have used Waterlox finishes for nearly 40 years, including Waterlox Marine. I love their finishes for interior work, but have not been impressed with their exterior products. I live on the NC coast. If you talk to people here who have boats, and are serious about using the best, most durable finishes for teak, mahogany, etc. there is little question that the product of choice is Epiphanes Marine Spar Varnish. The application process is lengthy and a pain, but the result is certainly worth it in my opinion, especially for a handmade piece of this quality. There are some other products out there that may approach Epiphanes that are not as tedious to apply, and Sikkens Cetol is one of them. Of course, these are just my own opinions, and I'm sure that whatever you use, the rocker will look fantastic. Great work.
