maybe to clean out any carbon build up on the hole....post a pic of the glow plug for easy explanation.......it bet the tip end of the plug body is a smaller diameter than the threaded part, with the element, a smaller diameter again, else how the hell does it fit in the hole.....taper seal?
if there is a carbon build up in the "hole" then this will make fitting difficult? and/or damage the fragile heating element, the bit that glows.......
as to copper grease......I have seen a table somewhere that shows electrolytic ? action between different metals....will try and find and post if its relevant.
I use copper grease for pad metal backing contact areas as well as general chassis bolts etc.....and red rubber grease for the brake hydraulics etc as its safe to use with the "rubber parts" ....mineral lub will make the rubber parts swell etc.
