The product's origin story is fantastic, too. WD-40 was created by three engineers at a fledgling aerospace outfit in San Diego with the awesome name, "Rocket Chemical Company." It took them 40 attempts to perfect the formula, the current head of innovation at WD-40 noted last week, and that's why the product is called WD-40. Water Displacement, number 40.
The first use for the product was sealing Atlas Missile's outer skin from rust and corrosion. It was only after employees snuck out some of the stuff to use at home that they thought about commercializing the formula.
