Oxidation fighting compound, WAS Re: copper

[J. Larry Hendry]

I don't know about Tweak, but a conductive, oxidation fighting liquid is
very commonly used in the utility industry when making bolted connections
that will carry hundreds or thousands of amps.  Even a small amount of
resistance will cause heating in these connections.  I don't think it is
particularly expensive.  I think the construction guys use two different
types - one for connections that go together and stay together and one for
switch contacts that will be closed and reopened repeatedly.  If anyone is
interested, I will find out more information about this compound.

Concerning the best metal for contacts, nearly all high voltage switches
are inlaid with silver at the actual contact points.  Nothing seems to work
better.
