So it's been about a month and some parts of my tank that I used pond armor on are still tacky. The majority is bone dry. I was thinking about having a fan blow over it to see if that drys it up.

The black part stays sticky forever, its the clear that makes it harden. Make sure your ratios are right and stir it well. I just put another coat over the sticky part and it worked fine.Yes the first coat didn't have this issue only the second
