Me too. I had high hopes for the epoxy.
When I get the tank out of the basement,
I've decided to strip off the plumbing hardware and the heating elements,
if they don't look too bad. But the leaky tank is out-of-here.
I'm not going to invest much time trying to find the source of the leak.
Maybe 90 seconds.. I've elected to avoid water tanks for as long as possible.
