The best thing I have found to use is thinned JB Weld with acetone. I rewound four motors a few days that were originally bare metal that I painted with thinned JB Weld. With tight winds, none of the phases had continuity to the motor. I thin it down so it is about as thick as paint, and paint it on. In some cases I have gone back with a second coat that was slightly thicker and added a second coat at the ends where the wire wraps around and is most likely to lose some of its insulation when pulled tight. I just painted another stator tonight with JB Weld.

The photo of two motors shows what I did a few nights ago. The motor on the left was done in a single coat. The one on the right required an extra dab in a couple places where the JB Weld was not quite thick enough at a few corners.

The other photos show the one I am working on tonight.

I have tried paint on insulation, but it rubs off too easily.
