Can i use this at (loudspeaker) magnet voice coil winding? haw do you think? is it the better then mg chemicals 4228 red glpt insulating varnish

Yes, and it should not be a problem. It has a much higher voltage insulation rating, however I used it in a 3000 volt transmitter power supply. Your voice coil (not used as a power supply speaker choke coil) application can use either one. Tony

Can be removed for resoldering?

When cured/dried it is very tough and cannot be removed by any solvent I know of. For de-soldering PCB's you can "burn through" the coating of a solder joint but be careful of the fumes/smoke.

What precautions should a hobbyist take when using Super Corona Dope at home?

I have never used any extra precautions when using it. I guess I would say be careful not to spill it as it is much more fluid that earlier versions of corona dope.

will this work on stater/alternator windings on a motorcycle magneto that is in oil? will it hold up to oil &heat?thanks

long-term, probably not. If it's immersed in oil, I wouldn't think you'd need to coat the windings anyway
