The brand WD-40 was invented in 1953 in San Diego California from Rocket Chemical in a small workshop of three people. NASA had to solve the problems of corrosion and protection of electrical contacts on its rockets. Asked its suppliers to invent a water repellent (in English: Water Displacement). They tried 1, 2, 3 different formulas... finally the 40th was born perfect and WD-40. Initially WD-40 was used in the aerospace industry and the military, but the product has appeared so versatile that employees of the Rocket Chemical used it at home too. In 1958 the inventor Norm Larsen managed to put WD-40 in a can. Since then, WD-40 is used in both industrial (aerospace, automotive, mechanical, etc.) and at home. Today, WD-40 Company, took its name from its famous product and has become a world leader.
