RE: horn ring lube

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

... while it is true that the grease does not enhance the conductivity it
does not form an insulating barrier between the conductors either ...
perhaps it should be called "inert" grease ... the spring in the horn ring
contact is quite capable of working through the grease to make a contact
point on the brass ring.  

I think the name dielectric grease arose from its use in ignition systems as
something to seal and protect ignition wires and spark plugs.  In that case
you need to be sure that the grease will do nothing to assist an alternate
path for the spark ...

... if you hadn't surmised, I've successfully used dielectric grease on my
horn ring contacts for years ... it almost seems like the gummy residue I've
removed from the OEM/PO is something like wheel bearing grease! ... BTW, I
also use anti-seize compound on my wheel lug bolts ... but then I also drive
a car with 2 Torsens ... I guess I just love to tempt fate ... :-)

	Right!!! Read it again... its an electrical INSULATOR. 

	You use it where you have two electrical components that you want to
	insulate from each other.
