Paint with fungicide

[BHOFM]

Checking out the paint store today and found a paint
with fungicide. For under sink and bathrooms.
It is exterior rated and has a "25 year" life.

"Prevents mildew, mold and rot."

"Can be recoated with any oil or water base paint."

"Can be thinned with mineral spirits." It is oil base.

Would this make a good first coat if one was not going to
epoxy?

It is not costly, $11 per qt.!
