The Corvair Service Manual specifically says to NOT use anti-seize. I
sometimes comply with that recommendation. However, I have used Champion
Spark Plug Lubricant CH2612 to good effect. This product is said to have
graphite and mica flakes in it to help heat transfer and is required on
aircraft spark plugs. Just don't get the graphite on the business end of the
plug or it'll ground the plug.

Curiously, the manual DOES specifically say to use anti-seize on engine
bolts going into aluminum. Apparently they thought for some reason that
spark plugs should be excepted. I don't know if the prohibition against
anti-seize was intended to apply to Champion CH26124 or just products like
Permatex 133K.

The only other place I've ever seen specific prohibitions against anti-seize
in a service manual is wheel lug nuts. The torque specification there is
calculated on having the lugs dry and lubricating them will cause them to be
overtorqued.
