Anyone ever use US composites epoxy? I know its a two part epoxy and used for marine boat building. I called and asked about it and they advised me that its 100% solids when cured. So I'm assuming it would be good for tank building. I've already used the epoxy paint from sweetwater and that worked perfect, but the price has gone up by $20 bucks since i've used it, plus they charge a $20 hazmat fee!! From what I understand, it shouldnt be toxic. US composites doesnt charge that fee, stating that it isnt hazardous, plus they are $20 bucks cheaper from my source. Anybody have some knowledge on this??
Using two-part epoxy for plywood tank

I haven't used that brand, but i did you LIS marine epoxy enamel used for boats and it was a 2 part mix.
pretty much any marine epoxy that's used for boats is safe for fish. I don't think they would sell a product that would harm our ocean.

I have used their Kleer Koat on plywood but not for a tank. I would think one of their standard laminating resins would be fine. Did they not recommend a specific resin and hardener system for a plywood tank?
The Sweetwater Epoxy Paint should absolutely be hazmat. It is basically a resin with strong solvents and pigments added. It is not a 100% resin system.
Epoxy Paints like Sweetwater go on a lot thinner and typically one can get much better coverage with them, so they are often cheaper once that is factored in.
If you don't require the structural strenght of a 100% resin system I think the expoxy paints are easier to use in some ways, although very, very nasty until cured.
I have purchased solvent based epoxy pool paints locally and avoided shipping costs. But that has been a long time now and I don't know how common they are since I believe the industry is moving away from them. Still, you might call around and see what you can find locally. Any sort of two-part, solvent based epoxy paint for potable water should work.
But absolutely factor in the cost of a respirator. The epoxy paints are still one of the most unpleasant products I've ever used.
You could always save yourself 50% on the cost and use US composites premium polyester layup resin and/or gelcoat.
