    quote Buccaneer:

    Super Corona Dope is good stuff, but I just use it on
    old, hard to come by, coils, as it’s spendy, but a little
    bottle goes a long way.

    That is good stuff – Way back in a past life, I used to use it on high voltage flyback transformers in old TV sets. The problem is that insulation eventually breaks down between coil windings internally where you can’t do anything about it.
