Plasti-mend makes note that the tank must be dry. When my galley tank failed years ago, I removed the tank from the trailer, cleaned it out, and let it dry out in the Florida sun. I could easily repair the seal around where the top is mated to the molded bottom and repair a crack on the bottom of the tank. After two days, I re-installed and also put plumbers strap in three places across the tank to limit tank expansion. I have had no further troubles. I can't even imagine doing this work while in place as you have done. I give you an A for persistence and courage.
