Sorry, ive used coppaslip since the 70's and dont think there is anything better, i will even admit to using it on shells in my own Fords

I've always used Coppaslip but after buying some nickel grease I think it's better than Copper so I tend to use that now.

Apologies, to clarify my earlier post, I tend to use the corrosion block grease on bolts ETC, preferring marine grade grease on pivot shafts and wheel spindles and copper slip on anything that could get hot, although it does say in their data sheet that it can be used at high temperatures, I haven't tried it.

As above, it's rare to take something apart that's been coppaslipped and find it stuck, generally pretty effective in reality.

There's more than one thing going on though, one being the grease within in which excludes moisture etc. Galvanic corrosion ordinarily needs promoting by electrolyte and ordinarily supplied by salt water solution from winter roads quite effectively.  Exclusion of electrolytes by waterproof grease and sacrificial metals the defense methods.

Straight "galling" of one metal against another in high torque loading a little more specialised in that nickel for stainless outperforms most others to prevent cold pickup and localised welding of two components. 

For really susceptible components in high water ingress locations, the marine type grease is possibly most effective if that's the main risk. Something like Duckams Keenol (don't think it's still made though) and has significant levels of zinc oxide incorporated was really effective.

This is all very interesting. Copaslip, it would seem, is fine. In fact anything is better than nothing!
I thought Nickelslip wasn't available because of the fact that nickel is now very expensive (in fact I believe trading in Nickel is suspended).
I was also told by someone else that Nickelslip was toxic (?)

Yes, very specific uses eg stainless both bolt and nut as the stainless has very high chance of picking up and welding together under torque load.  During tightening the bolt gets stretched with the nut compressing to give conflict with the two components as their thread pitch is changing in opposite direction to each other. Binding is fundamental to torque measurement too, correct lubrication is a fundamental part of working in this topic.
Opposite to this is brass fitings on oxygen cylinders as you can't use grease for risk of explosion, all joints, in oxygen acetylene for example, are dry.

N of course is the N-ickel in our new motive power of the future, batteries, in monumental quantities.

And what about the impact on the torque values?
Normally the numbers given in workshop manuals are rated for "dry" installation...
How much shall one reduce the torque if any anti corrosion lubricant is applied? -5%, -15%...?

I know only too well about the 'welding' of stainless steel. Whilst helping out a mate at a harbour in Lanzarote, I managed to 'weld'  a s/steel ball cock and fitting. No amount of force could separate them. Of course, I had fitted them dry. Lesson learnt!

Thanks to a forum member (Thanks Peter) I am now the owner of a tin of Nickelslip. Probably ought to place it in the safe!!

A quick research:

https://www.engineeringtoolbox.com/torque-lubrication-effects-d_1693.html

Anti Seize however claims to maintain 75% of the original torque specs...

https://www.antiseize.com/PDFs/torque_specifications.pdf

And Loctite suggest to reduce values by 20% when applying thread-lock...

Coppaslip 100%. I’ve used it since 1976 and never had an issue, not one.
