I have to outdoor light fixtures (four sockets) that have been empty
for several years.
They require a long extension ladder to get to them.
I'm afraid that the threads in the sockets will be a bit corroded.
Can I spray WD-40 into the sockets, let it sit for a while and then
install the bulbs?
You can, but it would be far better unless they're in better shape than
one would expect to do a good job of cleaning them up first. I tend to
use the automotive-style dielectric grease (like you find in tail light
fixtures, etc.) in outdoor sockets to minimize the inevitable corrosion.
Flammable, but not "highly" -- I routinely have used it on rusted
threads w/ a oxy-acetylene torch -- it flares up a little and smokes but
doesn't go "boom"...
It just isn't have a great deal of help for what OP's problem(s) most
Actually I have a can right here. It's not "highly" flammable.
It's EXTREMELY FLAMMABLE (all in caps)
As if it wasn't flammable enough, the propellent is propane.
Here's the more detailed warning on the back of the can:
Extremely Flammable. Keep Spray Away from: Heat, Sparks, Open Flame,
heated surfaces, and any other sources of ignition.
Disconnect electrical tools and appliances before spraying. Keep can
away from electrical source or battery terminals.
See, I said it wasn't "highly" flammable... :)
Can't you tell someone is (mostly) funnin' ya'? :)
Although I have used it as described although I do the spraying before
lighting the torch. It really doesn't even flare up good, mostly just
smokes and sputters a little. The propellant is long gone, by the time
one gets the torch lit, of course...
I have a potato cannon. I use an explosive propellant. You spray it
in, hit the sparker, and BOOM a potato goes flying a couple of hundred
yards. It is much more explosive than WD-40 (or else I would use
It is hairspray.
If you think WD-40 is explosive, you'd better seek a ban on hairspray.
I don't really compress it. I slide it in first. It does create one
heck of a seal, though. But I've never made french fries with it.
The spud goes out in one piece. I got "the long way" on the potato so
it's a good, solid hunk of flying flesh.
I've often thought about putting some sort of groove in the barrel so
I can get some rotation on it. they it would REALLY fly.
Compression's easy. Taper the inside end of the barrel slightly with
a piece of 100 grit sandpaper, so it punches out the spud
Range would be the same, accuracy would be better.
I've seen rifled PVC barrels sold online for just this purpose. Not
cheap, though. I wonder if you couldn't glue in a loose spiral-wound
piece of wire pulled from a bit of Romex for the same effect. Hope
it stays in after the third shot ;-)
Could you cut fins from cardboard and install them into the spud
at a slight helical pitch to add spin?
Aquanet has killed at least one woman who was stupid enough to ignore
the "Do not puncture or incinerate" warning on the spray can:
My curious mind wanted to find out how the lawsuit came out, and when I
couldn't Google anything more about it I posted to misc.legal.moderated
and let the legal eagles have a go at it. The most they were able to
find out is that the case is "still pending" and a defense montion to
dismiss it was denied.
