ok i need some help from you diy tank builders. im going to use a liquid rubber to seal my plywood aquarium. im having the hardest time figuring out the differences in names. some only in canada, some here in the states. if people can chime in and let me know the exact name of the product you used, the price per gallon, and WHERE you bought it id really really be thankful. my tank is going to be 4ftx4ftx12ft.
ive read 50$ per gallon all the way up to 100$ per quart? im lost. my major cost is going to be the 2 viewing panels. id love to cut cost in the sealing if i can. thanks in advance for the help. i really need it! btw im located in so california.

The various liquid rubber products end up costing a lot since they are only about 50-60% solids and need to be applied thick for water proofing. But I wouldn't necessarily rule them out for that reason alone.

If you've considered epoxy I'll suggest this one:

I haven't used this particular epoxy but have read great things about it. Think I read good things about their customer service as well.

With some of their larger kits the price is below $60 per gallon. And you save on shipping if San Diego is your part of Southern California.

On paper it takes a lot less epoxy resin to waterproof than a liquid rubber product. But if you start using fiberglass reinforcement in epoxy then the price starts to climb rapidly.

Just some food for thought. Hope you get some more feedback on specific liquid rubber products.

Max Acr on Ebay. Wonderful stuff, especially when paired with fiberglass.

I used "rubberize it" to seal the DIY top that I built. I didn't not however use it to build an aquarium, so I can't vouch for how great it is for that purpose.

It was easy to work with and not too costly, the only drawback I can see is that when submerged, it turns a brown color.
