A few of you are close...it was indeed called 'Rocket WD40' originally and it was the 40th formulation of a chemical developed for Convair to stop the skin of Atlas missiles going rusty.

Well, I`ve been using WD 40 for years and years to wipe rifles and pistols over when finishing shooting with no ill effect. Also use as a releasing agent on rusted parts, bolts etc. I also use Ballistol, which smells lovely and works well. I do not use WD 40 on internals unless to just clean parts.
'WD40' now appears to be something of a generic name term as I believe WD40**** (insert extra name tag here) products are available. Personally I have not seen them nor tried them ....

I've been using it on airguns for years, and have yet to see any detrimental afects.. for cleaning crud off externally, removing light rust, and also for cleaning bores. Also good for degreasing the internals of old guns.
Obviously, as stated, the guns need to be relubed afterwards with conventional oils, but as a crud remover / degreaser, I like it.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
97% of users agree that WD40 works like the hand of God.

Just to clarify the name, WD40's full nomenclature is 'War Department Oil No. 40'. All oils, lubricants and sealants used for military applications are allocated a number which is referred to on a list of items where the oil can and can't be used. WD40 is for use on machinery and vehicles for freeing screw threads, and is definitely prohibited for use on weapons and munitions as it can react with any explosive substance it comes into contact with.
The formula was released onto the civilian market in the 60's because of its popularity with mechanics and engineers.
Don't use it anywhere near your guns!!
I am an ex-army Ammunition Technician, and fully familiar with the use and mis-use of WD40.
not what wd40 the company says

its very good for removing the sticky residue left from take or price stickers from scopes or anywhere, spray on a sheet of kitchen towell first to prevent any going on lenses though.
