Does pipe dope work when the pipes are galvanized on plastic? I have a
plastic connector that needs to go on old galvanized for a temporary repair

sufficiently if the female end was plastic.

I've used it for stubborn pvc to pvc connections to stop a drip. Just
make sure the dope you are using is safe for pvc. I think PTFE is the
stuff safe for plastic, read the label.
