Alrighty then... here we go

WD 40 is not a lubricate, it is a Water Displacement product.

It is both.

It is good
for spraying on electronics to keep contact points dry and to reduce the
amount of corrosion

Yes, the contacts & mechanical switches


Too many people think it is an effective lubricate, it
is not.

Not for bearing grease, engine oil, or assembly lube... (and it will dissolve
any of these so should never be shot INTO a bearing or reel for LUBRICATION)
but definitely works for freeing seized parts, bolts, tools, etc.


WD40 IS INDEED a lubricant,

yes

and a very good one.

no, it's part lubricant, part solvent... it's viscosity is very low for just
lubricant, and it disspates rapidly. It makes a great chain cleaner for
motorcycles, and it also works well as a chain lube, as long as your willing to
reapply every 75 miles or so


It is NOT a water
displacement product

It works for me... as well as thousands of mechanics

and should NEVER be used on sensitive electronic
products.

agreed, not on a computer motherboard... but I use it for moisture
displacement/anti corrosion on all connectors, including the jacks on my
gps/bottom machine/radar/vhf equipment.

WD40 is
petroleum based and as such will indeed remove the sticky goop from
boat lettering.
(And perhaps the finish / fiberglass as well !)

Hmmm, not from what I've seen.

I've used it on automotive paint, boat gelcoat, fiberglass, ABS, metal etc. to
remove sticker goop for 15 years with no effect on the substrate, but it will
remove most spray enamels, and maybe even fingernail polish ;~
