Alright folks, I want to try something a bit different in the water channel arena. I plan to lay wiring and other components below the level of the water channel. ideally what I would like to do is apply a release agent (not sure what works here) and then use the concrete sealant from dap to form sections of water channel that effectively snap in and out. I plan to ask dap about release agents but if anyone else has any ideas on readily available materials/release agents for those materials, please let me know thanks Greg
