yeah, I was following his thread too and the entire time I was thinking how he could have avoided all of the issues that he had if he just went with the Sanitred since I had similar issues with the Pond Armor as he did. I didn't chime in at the time because I could tell he was getting frustrated and he was getting a hundred other suggestions as well and I could tell that he was taking them all with a grain of sand.
He had a previously successful build with the Pond Armor so I think he was pretty committed to getting it to work. IMO, I would be concerned about life expectancy on a brittle epoxy on a wood tank. If anything moves at all it'll leak again.
I used a bunch of the left over Pond Armor on stuff around mine and my parents house and it left me not impressed at all. The most basic thing... I recoated an old antique concrete bird bath that they have. It looked great for about 6months, but after that it bleached out pretty good in the sun and there is spider web cracking.. and this is on a solid piece of concrete.
I would say that any of the rubbery products would be a better option for an indoor wood tank than any brittle epoxy. I'm only partial to the Sanitred because of the success that I have had, especially when weighed against the massive issues I had with the Pond Armor. Seeing something work for me the first time was a feeling I can't describe.
