In 1953, a fledgling company called Rocket Chemical Company and its staff of three set out to create a line of rust-prevention solvents and degreasers for use in the aerospace industry, in a small lab in San Diego, California.

It took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40—which stands for Water Displacement perfected on the 40th try—is still in use today.

WD-40 Company, Inc., went public in 1973 and was listed Over-The-Counter. The stock price increased by 61% on the first day of listing.

Since that time, WD-40 has grown by leaps and bounds, and is now virtually a household name, used in numerous consumer and industrial markets such as automotive, manufacturing, sporting goods, aviation, hardware and home improvement, construction, and farming.
