When I was a kid my Old Man told me, “If you want a rusty gun, use WD 40.” He used Hoppe’s #9 solvent, and 3inOne oil to lube and protect his guns. If nothing else is available WD 40 can be used as a solvent, and it will displace water. But it is a poor protectant and too thin for use as a lubricant. Instead, you can use motor oil, white grease or petroleum jelly. In a pinch, Neosporin from your First Aid kit will work. =BCE56=
