If Kroil fails, consider a magnetic induction nut/bolt heater. I don't know what kind of dark magic this thing employs, but it works. Recently I pulled all the bolts out of a 1980s Fiero exhaust system. Soaking in penetrant did nothing. Less than a minute with this thing had them glowing orange and they all came out with the threads intact.
