It recommends using Anti-seize grease. The Land Rover part number is RYL105020L. The Zeta anti-seize grease, now available from Land Rover Parts. However it costs around £20+.
I did an internet search and found some for sale on eBay. Its was around £6 so I ordered some and it arrived today.
Easily a bargain. Grab one while there’s still some left!
