Anyone use this to lock M2 taper chucks/arbors?

I've seen it used for that but a clean shrink fit with heated chuck and cooled arbor and tap together with lead hammer does a great job and never slipped for me.

Is there a primer that goes with this for non ferrous metals?

I have used this on plastic, Alum and all steels....works well. Never used a primer

Will this provide a strong enough bond between a steel electric motor shaft and a bronze press fit gear?

its is pretty stout but i don't know i used it for a shaft that is moved by hand for a small mounted micrometer
