What is best anti-seize lube?

[Stig / Major Tom]

Copper based, or the silver stuff?
Want to use on caliper slide pins, exhaust header nuts, and maybe spark plugs, etc (- although some say don't use on spark plugs?)

Advice?

I've used the Permatex anti-seize compound (silver) for years on both bikes and cars and have never had an issue with bolts or spark plugs that would not release. As for not using it on plugs I go by the better-safe-than-sorry rule. Many years ago I had a plug shoot out of the head on a BMW 1600 head because I was afraid of over tightening. From then on I always used the anti- seize.

Not sure about caliper pins but there doesn't seem to be the precise contact of dissimilar metals in this instance, does there?
If you use it on exhaustx prepare for initial smoke and smell after which it doesn't seem to be a problem, although I'm sure if the heat limits its' effectiveness.
I don't hesitate to use it on plug threads when I think about it.

My memory is kind of vague, but I seem to recall it being best to use special brake grease for the brake components. Possibly synthetic being ideal?

This is what I used last time. My local shop had it in stock for not much money, and it seemed to be what I needed: https://www.amazon.com/Versachem-26189-12PK-Synthetic-Caliper-Grease/dp/B00C3ZA36G/ref=cm_cr_arp_d_product_top?ie=UTF8

Here's a ranked comparison of brake grease: https://wiki.ezvid.com/best-caliper-greases

I also remember making the assumption that it would be pretty easy to find a variety locally, which ended up not being the case.

I have always used the silver stuff on spark plugs and bolts into aluminum in bikes, cars and aircraft. there may be something better but I don't know what it is. Kinda one of those if it ain't broke deals.....

I use the copper (heat-proof) Permatex for no particular reason except that's what's in my toolbox and it works.

Just stopping by . . . yes I lurk once in a while, I'm still around.

For nuts and bolts I use the silver Permatex Anti-Seize Lubricant #81343
For brake caliber pins I use green Permatex Disc Brake Caliber Lube #85188
Can get at most auto parts stores like Autozone.

Best anti-seize is dependent on metal types, temp rating, and purpose, AFAIK.  I was told to never use zinc-based nevr seize on any fuel lines, for fear the injectors would be damaged or clogged.  Also, I was working on an oceangoing ship that had a back deck with many 7/8" threaded holes for placing eyes to secure conex boxes or other equipment.  The threaded holes were stainless, welded into a steel deck and had brass inserts (plugs) for when they were not in use.  Once a month the crew would remove, clean, and lubricate these plugs with Nevr-Seize (the zinc type). Every month we would have to drill and tap 5 or 6 of these (locked up) until starting to use petroleum-based grease rather than the nevr seize.  The mix of salt, zinc, stainless made the nevr seize act like a zinc anode and expanded in the threads.  After switching to plain grease, the plugs never were bound up again.
Apologies for long-winded post
