In my earlier effort at simulating water I used dark blue paint covered by several layers of Miniwax Gloss Polyurethane. Now that I am re-executing the water surface, I am wondering if I should use same technique. I like the technique because it is easy to apply, is very forgiving and mistakes can be fixed somewhat easily.
My decision was reaffirmed when I saw Steve Borichevsky's blog, "Shooting My Universe," a blog that I follow. He posted this photo which looked almost exactly like the water surface I achieved with my earlier technique. Compare these two photos, my backdrop and water surface on the left and one of Steve's images on the right.
