Yes Ej, that is exactly what I was thinking of.
I agree about the glossiness of the finish. I have 1" thick rocks in my tank that I have epoxied together to form retaining walls for different levels in my tank. When I used the epoxy to glue them together, I coated the entire rock with epoxy. It has an unnatural glossy look to it. There are ways to 'matte' down the finish so it isn't so shiny. I will get back to you on this.
