Just curious, what did you use before?My wife uses epoxy resin for table tops and crafts quite a bit and has asked if we could use it to seal our plywood tank build (2300 gallons).
To be honest, I have been asking the same question in my head.
First time building a plywood tank. I was thinking either Pond Armor or liner. But fiberglass and resin is way cheaper.Just curious, what did you use before?
