Does pipe dope work when the pipes are galvanized on plastic? I have a

sufficiently if the female end was plastic.

Yes you can if you do it properly.....first put teflon tape on the
female thread. This done in the same direction as the thread ((two
layers thick). Then cover this with a high quality pipe dope....not the
convience store quality crap.Do not overtighten.
