[Elecraft] K2 Toroid Wire Coating

[FlashandCo at aol.com]

For my first several toroid windings, I have used a Bic lighter flame to  
burn off the coating on the wire tails, followed by a sanding with the  
supplied P180 sandpaper.  I noticed it can burn up the wire fast and one of  them 
lost the coating up to the core.  Should I recoat, especially  where the 
lead may touch the wound toroid, like the horizontal RFC11?  What  is a 
suitable recoat for the wire?  Or am I being too picky?
