Dielectric essentially means non-conductive. The whole point of NoAlOx is to enhance conductivity and it contains zinc powder - some one said (I haven't looked into it much).
Theoretically, why would you want to put a non-conductive material between two current carrying members, when a conductive grease would do just as well at protecting from moisture? I see no reason not to smear dielectric all around outside, but it might end up in the current path just the same.
