Thanks fellas, I did finish cleaning the tank out this morning, wiped the whole thing down and dried it all up, and in that process I found multiple leak points in the deep end. Apparently I must have had my eye shut when I did my inspection after the first coat LOL There's spots where I can see the hardie plain as day! So today I'll be mixing very small batches of pondarmor and methodically going over every square inch of the tank. During the wipe down I found some small spots here and there on the walls and in the shallow end, but nothing like what I was finding in the deep end... LOL
