Rolling along very well now after a ton of work today. two full coats of drylock and a coat of black over that on all three pieces. Then two dry-brushed coats of Drylok to give it the base rock color with black depressions. After that I did some more dry-brushing with dark brown to simulate some dirt, as well as some dark green to simulate some algae. Then dry-brushed some white highlights on all the edges and raised portions to make the rocks look worn so it give it some nice depth to the rocks.
Some pics of it mocked up in the tank
Also started working on the side panels which will hide the intake tubes for the dual FX5 filters. Once the side panels are done then all that will be left on the background will be to coat it all in Pond Armor 2 part epoxy which seals it to durability and then I can start working on the cave lighting, tank lighting and substrate etc etc. This big background was a lot of work but I'm very pleased with the way this one is coming out.
