Just a nugget of useful information for anyone that cares to try it.
WD-40 / penetrating oil. 
I was at a mates farm recently and he showed me this stuff in action on some old rust tools and bolts that had been outside for years and years. 
I have never seen anything like it for releasing seized and rusted steel parts. WD would get nowhere near. I know the aviation industry use this product also
I just ordered a double pack of EBay with a small tube of there anti seize grease. Because if the penetrating oil is anything to go by, it will be amazing...

Wd 40 isn't really a suitable penetrative fluid, in the past I've had good results with plus gas and rp90 from Action Can. They make a great range of products.

Some one else might know more but does wd40 stand for water displacement and after 40 days it no longer performs this function.

as we keep saying WD40 is good for nothing other than slowing the spread of rush.

 

PlusGas is good as well.

"WD" does stand for water displacement, but the "40" supposedly indicates it was the 40th attempt at the formula.

We use ACF-50 at work with a lot of the old Jaguars and Tornados. It's great stuff!! WD40 also does make a penetrating fluid; that is also good!

ACF-50 is good stuff.

It's also good for cleaning plastic. I had some black plastic switches which had gone cloudy. A wipe with this stuff and they came up like new. And still look good years later.

Read somewhere it will, over time, damage rubber too ..

that is more to do with the propellant used. (may now be changed).

ACF-50 very popular in the motorbike world , good stuff but not cheap.
Also available as a bulk liquid.

WD40 is not a penetrating oil, it is a water dispersant.

Plus Gas is a penetrating oil.

I use ACF50 a lot but mainly for protecting against rust and I love it. It’s not a penetrating oil/fluid although it does penetrate, but not as fast as Plus Gas. If I’m having to soak something I often use both - the Plus Gas seems to help the ACF50 ‘get in there’ and the ACF 50 doesn’t evaporate like the Plus Gas. You could probably achieve the same with ACF50/Acetone or ATF/acetone

As above. I’ve been using ACF for years for rust protection and penetrant (just because it’s at hand) but WD still has its place. It’s a good cleaner and light cutting lubricant when drilling etc... I also use it to wipe down my work bench.
