Electrons only move on the surface of a conductor - if I got it right - and silver tarnishes; but the oil in BCE might prevent tarnishing. I don't think BCE acts as a conductor (maybe a poor one), but rather it enhances conductivity in the conductors it's applied to.
Copper will tarnish over time as well - I think I'd use a polish like Simichrome to clean either metal as much possible before applying the coating.
