I used the 3:1 epoxy from US composites. There was barely any fumes. I did it in my basement. You don't really need rubber. I just did it to add some color since epoxy is clear. The epoxy soaks into the wood so it's really waterproofed.

yeah to much of a pain to get it to seal id rather build a plywood tank with a glass window
okay guys heres my plan for water proofing the tank. im going to build the tank its self outta 3/4'' plywood and cut out my veiwing window then fiberglass the hole in side to water proof it. now my question being is it going to matter what type of fiberglass i use? i was gonna use fiber glass from Bondo, sound good? after fiberglassing it im going to paint the inside.
If by figerglass you mean polyester resin, I would try to find someting a bit higher quality than the Bondo resin. I don't know about Canada but I'm guessing you can buy something by the gallon that is better quality and ends up costing the same per quart/liter.
If by fiberglass you mean the mesh reinforcement, then avoid mat and use a fiberglass cloth in the 7 ounce range.
What are you going to paint it with? You can tint polyester resin if you want to stick with one material.
I'm still not completely clear. Was it resin or fiberglass reinforcement from Bondo you were considering? Or both?
I still think your going to want a frame for this tank, Just the plywood will not be able to hold up to the water pressure your going to create. Your going to need a frame and then put the plywood inside that, and you could always get cheap sheets to cover the outside if you want it to be clean. Look at a tank that is under built and look at the bowing, My tank is a perfect example, 1/2inch acrylic and the bowing is allot, I would not do the plywood only method. The overall 10 foot span is just huge and hard to not get the bowing. Your window will have a really hard time sealing on a curve.
