If anyone has any experience patching the glazing on insulators

No experience, but I would guess(tm) that porcelain sink repair
putting and paint might suffice if the damage isn't too extensive:

UV cure epoxy is another adhesive that might be worth trying:

The stuff is amazing. Smear it on, zap it for about a minute with a
UV flashlight, and it's hard as a rock. My dentist introduced me to
the stuff. There's also UV cure acrylic, but that's not going to work
here. I'm not sure of the electrical characteristics, but if the
chips are small, it probably doesn't matter.

I'm curious about the thickness that can be cured using UV.
If you have an 1/8" layer will it cure through to the bottom?
How thick can you go?
