"Trouble is the ferrite is conductive and the core needs to be glued in place."

Ferrite is not conductive. Iron core is.

Ferrite IS conductive; RTFDS. :)

Specifically, MnZn ferrite is a semiconductor, with modest resistivity in the usual form.  You'll measure on the order of 10s of kohms when you probe across a core.

NiZn ferrite is also a semiconductor, but typically much higher resistivity (hmm, I'm not sure offhand if this is a bandgap thing, or a doping thing, or an impurities thing), in the megs range.

you can fail a leakage/emi test with inductor magnet wire shorted to core shorted to chassis if its chassis mount
