lrp,
You should be able to get this grease at any hardware store that sells electrical supplies (wire, outlets, switches, etc). It is used on ground rods, when connecting dissimilar metals, connections exposed to the elements, etc. I started to use this stuff when I put up many of my amateur radio antennas. It really worked great. I thought I would give it a shot on my flashlights and have been very pleased with the results. I never have to shake or smack any of my flashlights to get full output.
One small bottle should last a life time. I use this stuff on any electrical contact point I can get my hands on, in all my flashlights. I even use this on 2 and 3 cell PR bulbs.
I'm concerned that the grease may overheat and smoke on a super high output incan bulb (flame throwers) flashlights. I've never tried it in this configuration, so I am speculating here.
There are other conduction promoters that are sexier and pricer (pro-gold) etc, that can be purchased at Radio Shack and Fry's. I have no experience with these high end products, but they may be better solutions for high output, high current configurations.
Good luck, TR "Greasin' up my torch"
