Not NeverSeize but pipedope, but I tend to agree. Another trick that
comes to mind is a large American Beauty soldering iron applied to
the plug, getting it hot enough to disrupt the pipe dope. (The iron
will not melt the case so that's no worry.)

You are better off heating the crankcase area with a heat gun and
turning the plug with the Allen wrench. Heating the plug will just
expand the plug into the case, whereas heating the case will expand the
aluminum away from the plug.

You'd think so, but what you are doing with the iron is two things:

a) Trying to overheat and destroy the pipe dope. (Then drip in some
Kroil...)

b) Breaking the bond between the plug and case.

Many a time I've gotten a bolt out by heating it orange with the
Ox-Acy torch. You'd think it would make life worse, but...
