Dan, we have a little wine bar here in Powell that just opened last year. They make everything on site and I believe they use the juice from L'Uva Bella (because all their offerings match what L'Uva Bella sells). Anyway, they have a bar with a wooden top covered with a coating similar to what you used and it looks great, too. It really shows off the grain of the wood and almost makes it seem glass-coated. From your pictures, the material on top looks like travertine. Is it?
