1996 Honda Civic Dielectric grease on spark plugs

Hello again.

I've read that dielectric grease is applied to the
non-metal parts of the plug and/or that surface
of the boot (where accessible) that slips over the plug.
And some websites say to put the grease on the
metal terminal as well.

I can understand the use of a non-conductive
material to prevent fusion/adhesion of a non-contact
point as w/ the ceramic jacket vs rubber of the boot
but not of the metal-to-metal contact mating surfaces.
Yet, people say that they do this.

The service manual makes no mention of dielectric
grease although it does rec anti-seize cmpd.
BTW, is a Cu-based anti-seize suitable for spark
plugs or is a higher temp Ni-based cmpd
preferred?

Thank you.

Yes, it seems like there is no uniform standard
for using dielectric cmpd. OTOH, if it can prevent
the plug boots from fusing to the ceramic jacket or other parts of the plug, it might be a good idea.
In particular, as it relates to removing the plugs
at some future date and re-using the plug wires.

I see from your profile that you are in Malaysia.
I visited Malaysia a number of yrs ago. Stayed at
the Federal Hotel in Kuala Lumpur. Rode the
express train to Singapore.
