I bought autozone fuel line and split it to apply to the edge. I put 1/8 inch closed cell foam on top to make it flush with the edge. I then covered the top and wrapped the edge with a trimmed Sport's authority yoga mat.
It makes the top look like a solid piece about 5/8 inch thick. Looks great, draws complements, safer, cheap, easy to clean, lightweight, and has held up fine in the four years since install. If the yoga mat gets ragged, I can remove it or just apply a new one on top for an even thicker look.
