Can anyone who's had experience building plywood aquariums recommend a good
2 part fiberglass resin or marine epoxy paint thats safe for aquarium use?
Home Depot and the boat marinas in my area don't have a clue.

No, they wouln't, but if youask the question "I have a wooden
boat I'm planning to store eyar round in salt water, what
whould I use to protect the wood" you'll get a better answer.

_The Living Aquarium_ (ISBN 0-517-39041-8) has instructions to
build all sorts of tanks out of all sorts of things; plywood,
glass-reinforced-resin, acrylic etc. For plywood they recommend
"varnish or resin". That's really all they say.

Everybody I know whose built a plywood tank (a handfull of
people I'd guess, over 30 years) used "marine expoxy".

Having said that I'm not convinced there's any reason to
build a plywood tank. You still have to buy the front glass;
decent plywood is not cheap (they recommend marine (mahogany)
ply which here is $80 a sheet) and large used tanks can be had
for peanuts if you're patient.

Any local big-time fish breeder near you knows where to get them,
and keep an eye out for cheap acrylic tanks i recycler.com. Figure
1/2 pound per gallon for acrylic and UPS will ship things up to
150 pounds cheaply. Acrylic tanks ship well glass does not.
