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.
