WD-40 Company does market other products - WD-40 Specialist that have other properties/uses, but the original forumla is definitely not. It displaces water and can prevent rusting. How many coats ???? have no idea. It doesn't really act as a penetrant - although it can produced some desirous effects for very short periods of time.
WD-40 is in my barn and I have more than one can cause I am always misplacing it. It is great to spray in dist caps, on spark plug wires etc., where wicking water is a problem. Why? .... cause it Displaces Water
When I have obstinant bolts - I get a can of Nut Buster, Solvo-Rust or Kroil if it really is stuck. Kroil is hard to come by up here so I have to get it when I is stateside. Course then we can run into the Crown Royal issue
