Rich.
AC or DC it won't matter, but I found about 35v was needed to get it hot enough to aid seperation of the overwind in my case. Obviously you want it to slide off without undue force, but not so hot that you can't hold it.
Oh, and it will be messy. Be prepared to peel off all the soft tar to reveal just the overwind doughnut. You won't harm the windings as they will be covered in a fabric tape.
