I finally bumped into my neighbor who used the synthetic teak on his boat. It is called Plasteak (Quality Boat Deck and Outdoor Plastic Furniture Products | PlasTEAK Inc.
) and it came out very good. He's doing the deck on the back of his powerboat in it now. The only thing I could recommend having seen his is to figure out a way to cover the edges as other than this it looks real good.
