Re: WD-40 and similar products

Tom,

On a trivia program on the radio they said it meant "water
displacement" formula number 40.

BTW, we use WD40 as a cutting lubricant occasionally for small jobs
in the lathe and mill where we don't want to use flood coolant. WD40
smokes under heavy cuts. Some of the other brands of spray type
penetrating lubricants we've used don't smoke ($tarrett's spray
lubricant is one that I know doesn't smoke). As far as comparing the
lubricating and penetrating qualities of the sprays, they all seem
about the same to me. Lowest price is what makes WD40 attractive.
