i used kerosene but it has to sit in the sun to get it hot so the cosmoline comes out of the pores of the gun

Cosmoline is defined elsewhere in Wiki land and is, short story, crude Vaseline. It is the gooey stuff left after all the various fuels, solvents, etc have been distilled out of petroleum. Petroleum jelly (Vaseline) is refined from cosmoline. All the armies of the world have long used cosmoline to preserve firearms and other rust able hardware for long term storage, by means of painting the goo on all exposed surfaces. It is far too sticky for use as a lubricant. TEKnapp

Cosmoline. Very difficult to clean off.

This has nothing to do with science-fiction but in former decades Sperm oil- yes from the Sperm Whale was used to lubricate fine watches and other scientific instruments. It was also part of the ingredients of the service lubricant Cosmoline- which does have a Russian sound, and a neat smell at operant temperatures. They used a lot of Cosmoline at Palisades Park!
