Hello, I purchased an upgraded stator rotor combo, but it had a small nick in the coating which I'd like to fix prior to install. Does anyone know the proper coating? Thanks in advance.

The epoxy on holding the wire in place or the actual wire coating? The wire does have it's own coating.

Hi Terry,
The chip is actually on one of the pole parts. So I'm guessing it's the epoxy coating - is that a specific epoxy type?
Thanks, Corey

The epoxy is only really there to prevent movement/vibration. It will need to be oil resistant and handle 250-280° heat. JB Weld make some good for 300°.

The hard part will be getting it to stick to the existing epoxy.

What about just patching the chip with some good RTV after very careful cleaning?

A product called Glyptol strikes my memory.
But my memory ain't that great.

The coating on the copper wires are something like schellac.

Reep - that sounds like a great idea actually. Then if it does peel or fall off it wont cause much additional issues either. I was worried about JB weld thinking it was sintered metal (which may not be true) and I've read about glyptal before though I have no clue what it is or where to get it...

I googled Glyptal, available from CRC, Eastwood etc... , insulating enamel paint. Used on electrical windings.
