WD-40 Test

Practice on with paint spray cans. If things go poof, you will have a near permanent visual reminder of why it may not have been such a good idea.
If it works for you without gumming everything up, use it. If it gums up the moving parts, don't use it.
Just make a trip down to the local filling station The factory uses 90 psi but, less will also work.
I haven't had much luck with the air compressor trick and it can be messy. Put on safety glasses, stand the can upright, drive a nail through the can at the highest point (don't stand over it). After the pressure is off punch a bigger or multiple holes and pour the WD in a jar. Use a pump sprayer, old Lestoil or Windex. I use bulk WD, no aerosol, cheaper and more convenient.

I buy the stuff by the gallon and use spray bottles, not sure about the propellent used in aerosol, might have some effect.
Just for the record, my test sample has been sitting inside my house for 5 days and it looks exactly like it did after sitting outside for 5 days.
Just some 30 weight oil. No signs of hardening or other undesirable stuff happening.
With my home refrigeration unit running (which it is now that the dew point outside is up to 50°F) the humidity is about 35%.
Maybe I should put the sample in something with water in it so it will be sitting in a place with a really high humidity?
I guess I'll try that.

Don't know about anyone else but our machine shop instructor told us that WD-40 sucks the oil out of metal so he had us lubricate the metal ways on the machinery with way-oil. Having seen metal treated with WD-40 rust, I go along with that reasoning. As far as patch lube goes, might be worth a try tho. I hear it might have some fish oil in it?

We used to use fish oil for tempering steel in the blacksmith shop, it seems to have some good qualities, but I don't know about lubing, viscosity?

We used a spray can of WD 40 on the combination lock we hung outside our Sutler Booth at the NSSA. It remained outside in the rain, sleet and snow all year round. I was instructed to use the long red straw and "shoot it up inside until some dripped out the bottom," after every Spring/Fall Shoot. All I know is the lock worked perfectly for the two to three weeks anyone went in and out of the Booth for over 21 years and counting the last time I was there.
I was also instructed that after a reenactment, if I shot it inside my Brown Bess barrel and coated it liberally, it would stop further rusting. Well, it did NOT work for that. Instead I used Sheath and more lately Barricade.
Yes, I HAVE seen the stuff gum up and solidify over the years on both Coasts in modern guns, so I would never use it on my lock parts.
Bottom line, there are far better cleaners and lubricants for guns than WD 40.

If I recall WD 40 kept a rusty lock working but didn't keep the lock from rusting in the first place.

I remember when WD-40 was first introduced. Was probably the best on the market at that time (?)
What I noticed then, and still today, is that any so called lubricating properties don't seem to last very long. Any oils seem to evaporate quickly. But it has name recognition and is the least expensive.
Today, there are simply better alternatives. After cleaning, that Barricade does in fact seem to work well.

If I understand correctly WD40 was formulated by the aero space industry to protect against moisture on metal parts during transportation. Please correct me if I am wrong, but I think part of the formulation is fish oil.
Partially correct and part of the mythology.
The more important questions should be; When did they stop using WD-40 to protect atlas missiles and what product replaced it?
Hint: Fluid film.

I think we should talk about Dawn dish soap!

I just looked up WD40 (again) and it stated that contrary to a popular myth WD 40 does not contain fish oil.
