If you are suspecting mold, this may mean the tank sealant was applied over either an improperly cleaned tank which left cleaning residue or the tank may not have been cleaned at all. I underline because this is assumption, I cannot see the application/mold for myself.
In either case, it is possible the new sealant application will continue what is basically off gassing, it will crack due to presence of solvent (gasoline) and then fail. It's up to you how to proceed.

ugh! Doesn't sound great, if that is what it is. I may have to get a steerable, lighted probe camera (neat tool anyway) and have a look inside by next spring. The company that did the work guarantees that for life and wants to look at the tank anyway, but I'd have to remove the bench seat again to get to the tank.
should I remove the gas cap (maybe cover with a screen) and allow air to get inside?
