Remoil
If you want a technical answer, I do not have one. All I know is that it does and it works very well. It is very very thin, not a heavy waxy substance one would normally think of wax as. Give it a try. I have been using it for many years and it has NEVER let me down!
Remoil is also about the best lubricant I have ever used on non firearm household items as well. I use it on sliding doors, door hinges, tools, machinery, knives. etc. and just about ANYTHING that needs lubrication and rust prevention where you don't want a messy greasy staining residue. It does not collect dust and debris at all. I carry a carbon steel pocket knife all the time and I tend to sweat a lot in the summer. I have found no better product to protect it from rusting then the Remoil. GREAT STUFF!!
