I would be concerned that the chemicals so deposited could CREATE problems
with electrical circuitry, especially when there is any contact arcing. Is
the resistance of the dry material infinite? What might the voltage limits
be?
Maybe okay for 12 volts automotive systems, but not for 480 volt power
distribution?
I remember using Freon TF and Freon TMC for cleaning high voltage (20KV
circuit components before potting them. Choosing the right cleaner was a
real big deal.

Actually WD-40 worked great in old automotive distributor caps to
displace condensation, 20,000-40,000 volts and plenty of arcing.

I suspect dam few to none. Having retired from the automotive industry
and having been the service manager for an automobile dealership I can
honestly say that I have never ever witnessed or heard of a sign,
sticker, label or what ever indicating not to use WD-40 "under" the
hood. We used cases of WD-40 in the shop, and under the hood.

WD-40, Water Displacement- formula # 40 is a **** poor permanent
lubricant. It works great for helping to loosen rusted nuts, bolts, and
frozen assemblies but the lubricating qualities are very short lived.
AND of course to displace moisture. Lithium grease is a much better
choice for a long term lubrication of hinges.

Contacts do **NOT** corrode. Contacts may tarnish being made from copper,
brass, silver and gold.

Spraying it on electrical equipment to displace does not mean into the
conductors. When you have water in your electrical conductors you have a
bigger problem.

contacts WILL NOT tarnish.

If by "a few" you mean "zero" then this is probably true.
WD 40, when used as a lubricant on something originally lubricated
with grease, CAN remove the oil from the grease, leaving behind the
"soap" (sodium stearate in some cases, lithium in others, plus a host
of others)- which will cause mechanisms to stick.

As for electrical contacts - on sliding contacts like many automotive
switches, and at low voltage and current, not likely to cause much
problem - but any arcing in a switch with "oily" contacts WILL cause
carbon build-up - which CAN cause high resistance, heating, and
burning of contacts. High voltage and high current contacts must be
CLEAN or lubricated/protected by an inert grease (dialectric grease)
that will not burn and protects against corrosion.

Spray WD-40 (aerosol) has (or at least had) a flammable propellant,
which, if used on an arcing contact - or in proximity to an arcing
contact, CAN ignite - with rather spectacular result if, say, inside a
distributor cap.

There are NO manufacturers that plackard their under-hood areas with
prohibition against using WD40 under the hood.
It is EXCELLENT for drying out damp ignition wires - even though there
are better products, which help seal the wires against moisture for a
longer time - but NEVER use "ignition sealer" - the plasticy coating
if compromised at all, just traps moisture in the wire, making it
worse - and impossible to dry out with WD-40 or anything else.

It does not stay on the contacts very long - and even there it CAN
cause carbon build-up on the electrodes - which is blasted off by the
next couple of "lightning strikes" - and is not a problem since the
"electrodes" are not "contacts" - i.e. - they NEVER touch.

Many contacts DO corrode, depending on the environment.
Brass sure can corrode - so can copper.
However,arcing, and the associated transfer of metal, is a more
serious problem - even with contacts of tungsten or platinum. (look at

period of time in a standard "kettering" type system)

OF COURSE they want to sell that attribute. But ask an engineer if
they'd use WD40 as a lubricant.

Next, you'll be telling me that Pepto-Bismal has no bismuth, and that
Kaopectate has no kayolinite or pectin (it used to, but no more;
actually, now Kaopectate IS Pepto-Bismal).
