3mX0.6mX2m plywood plan - Please advise: Super Laykold vs Durapond? (South Africa)

[resma]

Hi

I'm planing on building a plywood tank, using local (South Africa) materials.
From the experience of anyone who has used both, or one of A.B.E's Super Laykold and/or Durapond to waterproof plywood

1. What are the advantages of one over the other?
2. What's the life expectancy? 3 years? 10 years? 30 years?
3. What sealants work well with Super Laykold or Durapond? Does 3M 560 do? (bostick's marine silicon sealant doesn't)?
4. What other S.A. materials should I use for strengthening/pre-cotting the plywood, that work well with either Super Laykold or Durapond?

Many thanks
Cheers

Hi.

Also in SA. Built a plywood aquarium for a friend 15 years ago. One layer of fiberglass. (Did a very bad job lots of bubbles) Sanded and applied Durapond Tank is still running. It has leaked but only around the silicon seal. Was just seeping very slowly. That was after ten years. Cut the silicone and re did it. Nothing wrong with the pond seal that we could see.

Planning my build for the new year. Slightly smaller that yours.
