I recently purchased a liquid rubber product called Rubberizeit! (www.rubberizeit.com) Its been used to make plywood fish tanks and is advertised as aquaponics safe. I intend to use it as a liner in my GB, FT, and sump. I was wondering if anyone else has used this and what their results have been?
I haven't used it yet, as I'm currently fiberglassing the corners and bottom of my plywood GB. I have been waiting for a stretch of sunny weather. The product has a 7 day cure time.
So anyone try is stuff yet?
