I guess I used the wrong word. "Corrosion" is a general term for "rotting" I
was thinking of the term "rust". Not from the Griswolds... LOL.

Thanx for being so polite, OCD. It keeps the posts more honest and makes us
educate ourselves in correct terminology.

Many contacts DO corrode, depending on the environment.
Brass sure can corrode - so can copper.
However,arcing, and the associated transfer of metal, is a more
serious problem - even with contacts of tungsten or platinum. (look at
a set of ignition points that have been in service for an extended
period of time in a standard "kettering" type system)

Spraying it on electrical equipment to displace does not mean into the
conductors. When you have water in your electrical conductors you have a
bigger problem.
