The professor had something to say about the formulation and its relevance as a gun oil. “I don’t see any sign of other additives such as antioxidants or corrosion inhibitors. Since the unsaturation in these oils, especially linoleate residues, can lead to their oligomerization with exposure to oxygen and light, use on weapons could lead to formation of solid residues (gum) with time. The more UV and oxygen, the more the oil will degrade.”
