The military does buy shotguns so I can believe it is cosmoline. WD40 and CRC 556 are recommended solvents. It melts at 113-125 so hot soapy water or steam cleaning works. 40+ years ago the cleaning company I worked for would steam clean it off the surface of imported cars(BMW??). Problem with "elbow grease" was that any dirt or grit stuck to it would result in scratches.
