Preferred anti-seize compound for spark plugs?

I 50+ years of installing spark plugs 95% of the time they are gapped correctly. So you still really want to check them. If you use a gaping tool you won’t damage them. I don’t believe those numbers refer to a gap

Thanks Bronsin. I appreciate what you are saying, but I wonder because of what has been said in another thread on this Forum.

This Forum Thread Spark plug gap? suggests that 11 refers to gap, perhaps 1.1 mm. CT Scott in that thread also says: "Iridium plugs come pre-gapped, as you can easily scrape or crack off the coating while gapping them."

So I am wondering if I should really even check the gap. I used to clean and regap spark plugs all the time years ago. But they were not Indium plugs that lasted 100K+ miles. It seems to me that they might have lasted 20K miles and had carbon deposits on them, etc.

Any more comments will be welcomed, taken seriously and processed.
