Anti-seize on spark plugs?

[vwhugger]

On another forum there was a discussion about whether or not to put anti-seize on the spark plug threads when replacing them.

I have 2 Yaris' and have replaced the plugs once on the 2012 and three times on the 2008 and have never put anything on the threads and have never had any problems (seizing or stripping the threads). I've used Iridium plugs of different manufacturers (can't remember the brands).

Most comments on the other forum was that most people do put something on the threads.

Anyone want to comment on this and share your experiences?

I might add, the plugs have always been changed at about 120k intervals and have never been removed in between those intervals.
