WD (Water Displacement) 40 is great for water displacement and other things.
It's not so good for freeing up rusted nuts and bolts, which is what most people use it for.
Plus Gas is very good for that because that's what it's designed to do.
WD 40 should never be used on padlocks, guaranteed to gum them up every time.
