Old School Was to Always Anti-Seize Spark Plugs etc. Times Have Changed..... Most "All" Spark Plug Mfg's Suggest "NO" Ant-Seize on Spark Plug Threads.. (It Changes the Torque Value Loading Immensely) Good You Tube Video to Explain is at

I use AC Delco Iridium plugs, and the threads are chrome plated so NO anti-seize required.

No anti anti seize. It does act like a lubricant like u were saying. I just make sure my motor is cool before removing them. Then your plug holes will be all lubed up unless if you clean them out. I would stay away its just bad and unnecessary iridium plugs over 100k miles and could damage the threads somehow. I've used it and it doesn't make any difference except for the black burned goo left on the threads when you take them out.
