Glow Plug Replacement

[tamrsoft]

When replacing glowplugs, does anyone have a recommendation for the grease to use on the threads, ie copper or silicon grease etc or any other precaution to assist future removal ?

I used copper grease on mine...the only reason being that i already had some in my workshop.

Copper grease, but only a little.
