Can Ballistol be used in place of other multi-purpose oils/lubricants/protectants?-

Of course, Ballistol can do whatever other lubricants/protectants can do. Use it on tight or squeaky hinges, on door locks, padlocks, for the maintenance of gardening tools, lawn mowers, scissors, pocket knives, as sharpening oil, on bicycles, motorcycles, your model train, skateboards or roller blades, ski bindings and edges, etc., etc. But Ballistol does more. It can be used to polish silver and brass. And it will even protect WET surfaces.
