It will work in a pinch, but expect a lot of trouble after a
while.
The 'WD' stands for 'Water Displacing' - the stuff was formulated
for spraying on recently machined steel so that it wouldn't rust.
It penetrates the machining marks and displaces any moisture
therein - then the solvent evaporates, leaving behind a film of
tenacious sticky grease. It works well as an 'emergency'
lubricant on sticky parts, but plan on giving the thing a proper
clean & lube afterwards.
Contact cleaner is often little more than a little mineral oil in
alcohol - sort of a low stress WD-40.

As long as we are way out on this trajectory. . . Do any of you
know whether WD-40 can be used to clean electrical contacts
(mechanical switches and volume controls in hi-fi equipment)? I
seem to recall that some people have done this.

FWIW, the WD means Water Displacement. The stuff was
originally designed to displace water in rocket engines. It
works well for old style ignition systems that have gotten wet.
Spray it inside the distributor and on the wires, etc. It will
usually let the car start.

Noooooooo. You never oil a shutter because it accumulates crud
from the residue. You clean shutters with naptha because it
leaves minimal residue.
Yes, you might as well send it on off as the WD-40 will gum it up
when you least want it to. For lack of labeled "Naptha" you could
have used a little lighter fluid or Coleman fuel.
