Doesn't the 'WD' bit stand for 'water
displacement'? i.e. it's not
Either that or 'Water Displacer'.
designed to be a lubricant at all (and hardly
surprising there's some
waxy junk in there)
It's _supposed_ to leave a waxy flim behind, so as to keep the water off...
It's great if used for that (to keep the HT side of your car's ignition
system dry, to keep rust off the garden tools, off the steel rods you
keep in stock, and so on). But people seem to think that because it's
oil-based and because it's thin when it comes out the can, it must be a
suitable lubricant for fine machinery. That is what I object to it being
used for (mainly because said machine ends up on my bench a few weeks
later and needs a complete strip-down and rebuild).
I have a feeling the '40' bit is meaningless and was just chosen because
it rolled off the tongue nicely...
The norammly-quoted legend is that it was the 40th formula tried...
