WD40

[snubbyfan]

WD40? Back when I was a maintenance tech at the Rubbermaid factory in Winchester Va, I'd use it as a cuttin' lube for drilling out stripped manifold threads and tapping them for a hardened steel insert on multi-ton plastic molding presses.
Another thing I used it for was on the seams on the bed of my '87 Toyota 4wd truck to try to prevent rust. Delayed the inevitable but it rusted anyway.
I never came near a gun with it.

I have used WD-40 for the past 51 years for firearm maintenance and have yet to have a problem of any sort with my guns. Cleans, lubes, and prevents rust. No gumming up either.

I've had my fair share of pristine looking pistols brought to me by academy cadets (who fear "white glove" inspections), reporting assorted malfunctions experienced during their live-fire range sessions. Sometimes it's happened when academy graduates returned and experience malfunctions with their "clean & lubed" pistols when attending their first agency qualification session.

The common denominator has often been along the lines of, "But I used WD40 to clean and lubricate it!?!" When pistols start to heat up after a mag or two, clean/dry guns don't seem to run as well as clean/lubed guns ... or even dirty/lubed guns. Go figure. I cleaned and lubed the guns using one or another of the normal gun products that rotate through the bench ... and the guns suddenly worked as intended.

I use WD40 on some car parts, gardening equipment and door hinges.

Lots of good products being sold for use on firearms. Nice to see some being offered that are less toxic, too. However, you still need to read the labels. Not only for potential safety precautions, but to make sure whatever product you want to use is appropriate for the materials on your firearms (steel, aluminum, wood, plastic, etc).

Is it OK to use WD40 on your weapons ?

No . . . . .

Considering it was developed as a water displacement and used to prevent corrosion in nuclear missiles I feel pretty confident it's not going to destroy my guns, if it does we're in a heap of trouble with our nuclear deterrent.

I've used it from time to time. Never had a problem
