I'd say no. Keep in mind that the insulation will see 50-100kv+ at the ends 
with 3 layers. Even if it doesn't punch thru it (which it probably will 
unless you put gallons of the stuff on) it will simply arc around it 
instead of shoot sparks off the doorknob. HV transformers that you see in 
substations use an inch of oil + pressboard for every 11.5 kV on the 
winding. I'd simply take off all but the first layer rather than take a 
chance on it destroying itself after it's turned on.
