Yes, it does stand for water displacing, but I figured that refers to the water
that's in the rust of rusted parts. For drying ignition parts I've seen
silicone spray; using a flammable spray like WD-40 seems a bit iffy. Also, one
finds WD-40 sold (in bulk as well as cans) in machinery catalogs, far from car
ignitions.
And I've seen plenty of warnings against WD-40 in forums discussing
metalworking machinery and firearms, or gunsmithing reference books.
