...for a probe (in the sense of investigation). Not quite but will do 
I used corona dope about 23 years ago, once, when I had to hand-wind a pulse transformer that was supposed to withstand 5000V p-p and it id but I saw corona on the transformer's pins, so I used it.
Worked well.
But it did not impress me as a heat-resistant, hence the doubt here, especially in light of the fact that we are not looking to achieve high voltage insulation, so withstanding voltage is not one of the requirements.
In fact I wonder if a simple thing like a touch-up enamel for gas ranges is what would work.
I used it to paint my ballast tube when restoring my Stromberg Carlson AA5, and those get pretty hot, and it stands to heat well (it is intended to).
