When WD 40 was invented in the early 1950’s in San Diego, California its intention was for it to be a water displacement formula, “WD” for short. The intent was for it to be used by Convair to protect the Atlas missile from rust and corrosion. It wasn’t until the late 50’s that the WD 40 company made it available to consumers. Because of the numerous household applications for it. What made this product so useful to households and early firearm owners was that it came in an aerosol can. Nothing on the market was offered with such a feature making it quite easy to aim the penetrating oil and specific spots and locations.

Due to that ability, the airline companies started using the product as well in the mid 60’s to help prevent rust build up and clean airplane parts on numerous aircrafts. What made it so easy for the aircraft mechanics was the ability to spray the formula to tough to reach spots.

Penetrating Oil Function –

To give WD 40 the ability to be used in an aerosol can, the oil has to be diluted with hydrocarbon. Which gives it the low viscosity needed when using an aerosol can. Therefore, once sprayed the hydrocarbon evaporates, leaving only the oil behind. However, because of the low viscosity, WD 40 is not always the best lubricant. Therefore, this is why gun owners and gunsmiths started to use motor oils because it left a higher viscosity oil behind. Hence, allowing a gun to not have to be oiled quite as often. This also led to more solvents, oils, penetrating oils being specifically manufactured for the firearms industry.
