WD Stands for Water Displacement and it took the developers 40 attempts to get a formula which worked. Convair, an aerospace contractor, first used WD-40 to protect the outer skin of the Atlas Missile from rust and corrosion.
WD-40 is easily recognized by its blue and yellow can with the red cap. It comes with a little red straw that is stuck into the nozzle to help direct the spray. Recently, to combat the inconvieniece of the straw, WD-40 released a new design with an attatched straw on a hinge to increase ease of use.
