Tim--

The only problem I see is that Kopr-Shield is recommended for copper 
to copper connections ONLY.
Whereas Penetrox is designed for aluminum to aluminum or aluminum to 
copper use.

Kopr-Shield Colloidal Surface Treatment
Kopr-Shield compound is a unique homogenized blend of pure, polished 
colloidal copper, rust and corrosion inhibitors that simultaneously 
protects, lubricates and enhances the conductivity of the mating 
surfaces to which it is applied. Extremely adhesive, Kopr Shield 
compound flows smoothly into uneven contours and voids, making 
application easy, protection and lubrication complete and positive. A 
stable compound, it will not settle-out, thin, thicken, harden or dry 
out under the most severe environmental conditions.
For use with copper products only 4 oz container with brush.
