Anti seize compound ?

[Sargan]

Going to be assembling a new gravity smoker. (Think auto feed charcoal BBQ)
Been suggested to use anti-seize compound on the various screws & bolts.
They are typically M4 Steel black painted machine screws.

Any suggestions for an anti-seize paste /thread dip.

I would run a tap through the nuts so they're nice & sloppy.
Copper slip because it's the only paste I have.
The old-timers used to put soft-soap on high-carbon tools during hardening to reduce scaling - don't know long it lasts.
