PS: The US Government put out a contract back in the early 50's for a
solution to the old Jeeps that when driven through streams and the like
would get water in the electrical system and they needed something that
would work to displace the water quickly and allow the troupes to move
on. The company that finally got the answer tried 40 times with various
compounds before they were successful. The reason was it had to allow
electrical current to continue and not be blocked by the compound.
They named the product WD-40 (Water Displacement - 40th try)
There are so many uses that were found for this miracle spray later, but
many have forgotten it's original purpose.
WD-40 is cheaper than ether and easier to find.
Here is the website that has the details of the history of WD40, read
the second paragraph.
