I am not sure why you are being downvoted but you are absolutely right: it is even in the name (WD stands for 'Water Displacement'). My reaction to this article was a huge: 'why?'. WD-40 is at best mediocre at everything it is used for. Wurth makes much more capable compounds for the came purposes. Their penetrating oil is unmatched. I guess as part of the popular culture, WD-40 has its value but I am not sure its chemical properties are all that unique.
