I refrained from doing the remaining teak on the boat as I wanted to see how the product held up over the first season. I was looking for any indication of yellowing or hints of orange tint. In addition to the pieces shown in the thread, I also finished the teak flag pole which I ended up mounting to our house to extend it's exposure to the elements. It was outside for the Summer and Winter of 2010 (New England). So far, I don't see any reason to complain or notice a degradation in the finish. I'll be working on the rest of the boat this Spring/Summer (shown below sanded and cleaned but not finished).
