I'll agree with Joe. For over 30 years (well since 1966 when I got my first
Jaguar, continuing from 1971 when I got an alloy head Hillman (we still have
it) and now with the Range Rover, I've only ever used a general purpose
grease on the plug threads with no problems with seizing.
However, I read a while back that one should use anti-seize compound on the
plugs. So I did - I had some Permatex aluminium anti-seize in the garage.
Big mistake! The next time I went to pull the plugs in the Rangie, I really
thought I was going to strip the threads in the head. It obviously wasn't
suited to the application. I've gone back to grease and the plugs don't
seize.
