We had Food Grade Never Seize, in which the glass is ground up much finer. It doesn't work as well as the standard, but federal regulations mandated food grade ( We made breakfast cereal.) Also, just for information,we had some guys trying to use it as a lubricant, like putting a dab on a new seal instead of a grease or proper lubricant. Its abrasive and should not be used for that purpose.But what I'm wondering about, is how much of an insulator do you think this seize creates? The plug grounds through the threads right? It would have to be giving up some continuity and possibly change the heat range in the process? ...
