That sounds like "not quite" a shorted turn (yet). If you get a shorted 
turn, the epoxy would typically bubble (melt, etc.) all the way around the 
turn. But if it's just in one spot, maybe it's just a damaged spot (nik, 
abrasion, etc.) developing corona between adjacent turns. Probably just 
inspect, smooth out the damaged area, then recoat that specific area.

Take care,
Bart
