That's what the manufacture has been telling the dealer techs for some time now , With the extended tip Ford plugs you only apply anti-seize on the metal housing for the extended tip and not the threads ......I've also been told it messes with the higher voltage plugs acting like and insulator ..

I should have been more detailed.  They are blaming the use of anti-seize for plug breakage.  I'd blame the monkey turning the wrench and if that's not the case, I'd be looking at a possible defect in the plugs themselves.

We still use it never had any problems. We don't let monkeys touch the cars

This subject pops up all the time. "We" all know that the Sparking Plugs are better built and use superior metalurgy (Except for the Ford 3 Valve) but in the 70's the Navy was using pretty good stuff in our S-2G engines. It was a Court Martial Offense to not use Anti-Seize on the Plugs. As far as an insulating issue? I haven't put an Ohm Meter to a Dolope of the Paste yet, but isn't most of it impregnated with Copper or Aluminum? I have read where guys using it on the Boots had major misfire issues, so to me that lets the air out of that issue.  Some Guys Glue an Engine together, I assume I may have to work on it again someday, and would prefer not having to destroy it to take a part off.  I do however use a light oil to thin mine out, WD-40 type of stuff PB Blaster works, but evaporates quicker so your doing it more often.
