I guess my thread got hijacked

, but here is more about WD-40:
_________________________________________________________
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.
Convair, an aerospace contractor, first used WD-40 to protect the outer skin of the Atlas Missile from rust and corrosion. The product actually worked so well that several employees snuck some WD-40 cans out of the plant to use at home.
A few years following WD-40's first industrial use, Rocket Chemical Company founder Norm Larsen experimented with putting WD-40 into aerosol cans, reasoning that consumers might find a use for the product at home as some of the employees had. The product made its first appearance on store shelves in San Diego in 1958.
In 1960 the company nearly doubled in size, growing to seven people, who sold an average of 45 cases per day from the trunk of their cars to hardware and sporting goods stores in the San Diego area.
In 1961 the first full truckload order for WD-40 was filled when employees came in on a Saturday to produce additional concentrate to meet the disaster needs of the victims of Hurricane Carla along the U.S. Gulf coast. WD-40 was used to recondition flood and rain damaged vehicles and equipment.
In 1969 the company was renamed after its only product, WD-40.
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.
In 1983, WD-40 Company sales reached $50.2 million. Many companies attempted to introduce imitation products, going so far as to copy the distinctive blue, yellow and red colors of the WD-40 can.
In 1993, WD-40 Company celebrated its 40th anniversary by breaking the $100 million sales mark. That year the company was also listed among the Top Ten Most Profitable companies on the NASDAQ exchange. Not bad for a company with only one product!
WD-40 was found to be in 4 out of 5 American households (it seems everyone has a can or two) and was used by 81 percent of professionals at work. Sales had grown to more than one million cans each week.
The most interesting piece of WD-40's history is the uses for the product, now numbering in the thousands. The uses include everything from silencing squeaky hinges and removing road tar from automobiles to protecting tools from rust and removing adhesive labels. But they get a lot crazier than that.
