However, the soap dispenser leaks, how I don't know. No breaks, just
slow
leakage from ??? I retired it for a while, then decided I WOULD
solve this problem.

I thought of pouring some kind of glue or? into the dispenser
and swishing it around, hoping it would coat all around inside at the
base.

Only things I can think of is a hairline crack or porosity of the ceramic
itself allowing liquid to weep.

You can try wrapping it in a paper town and watching for it to absorb the
liquid and show a spot.

In any case, it first you'd have to drain and rinse well. That will be a
PITA, but you have to get the soap out for anything to cling. Then you
could try some sort of thin epoxy and swirl it around, but most epoxy mixes
are too thick to work well. Same with polyester resin. My guess is that
the smart people here will think of a good liquid that would leave a coating
and be thin enough to easily swish around and drain.
