That sounds like another good use for WD 40 but now the original
use. I came directly out of college to work as a mechanical engineer
for General Dynamics here in San Diego and spent my total carrier
working for them in the Aerospace business. I was original assigned
to work on the Atlas Missile. It was the first rocket designed to
launch an atomic warhead on Russia. The Atlas was a long cigar
shaped missile with the fuel tanks made by welding 10' diameter round
sections made of hardened 321 SS. The round sections were joined
together with an overlap of a few inches and welded together with a
continuos spot weld seam which sealed them together. On each side
of the seam weld there was another ring of spot welds about one inch
apart for reinforcement. This overlapping joint is what caused WD 40
to be developed to displace moisture from this overlap to prevent
corrosion around the exposed spot welds, but don't ask me what it was
made from. The Atlas was first developed for the Air Force to be
placed in silos around the US for only a few years, until solid fuel
rockets that were big enough to launch an atomic warhead could be
developed. It lived on to place the first man in orbit around the
earth and many other spacecraft and is still being made today in
Denver by LM, but it now flies with Russian engines because the are
cheaper then the US made engines. This WD 40 discussions has brought
back many good memories.
