Ummm, as far as I know WD-40 (WD stands for "water dispersant") is just a light petroleum
distillate product that contains no conductive materials.  Of course, there's no list of
ingredients on the can...  But one of the suggested uses is sparkplugs and spraying
conductive stuff on sparkplugs sounds like death to an engine to me.

I would guess that there was some other conductive material such as carbon dust, graphite
dust or powered metal that was slurried by the WD-40.

My bet is that if you take WD-40 and spray it on glass and then test the glass for
conductivity (whether wet or dry) you would find it quite unconductive.
