Several years ago I couldn't find my gun grease but I had an eight ounce tube of dielectric tune up grease out in the garage so I used that. I frankly love the stuff. The only problem is it is transparent in a thin film so it's difficult to tell if you've lubed enough.
I know it doesn't dry out because that's what they use in intermittent wiper controllers and I've opened them up after thirty years and the grease, where not contaminated with thirty years of copper powder and dust, looks like it just came out of the tube. It holds up to water in my fishing reels and stays where it's put. Great stuff.
