This has happened to me before, 
I just use some super fine grit sandpaper to remove the carbon then I paint a couple layers of polyurethane onto it. Though you may want to use what ever you originally coated the coil with to being with vrs the polyurethane.

Subject: [TCML] climbing sparks 

Just when I thought my coil was working well, I discovered climbing sparks on the back side of it! I never ran it more than 20-30 seconds at a time, but I notice about 5 tiny burn marks about mid-way up. Is there an accept method of repairing the problem? The winding is still intact, but there may be a shorted turn. Thanks / Dan
