Building Coils Pt. 2

Having been a wood worker for many years I cannot stand to leave anything unfinished or unpainted.  The coils look great but I am not sure if I should coat them with any type of clear coat.  I don't want to use shellac or varnish but I am thinking about a clear Polyurethane.

Any advice would be greatly appreciated.

I like spray shellac best, but have also used  a  clear acrylic varnish (crystal-clearwith good results).   Poly is probably ok, too.

Unless you want the "candy apple" look, I'd stick with spray cans and avoid the brush.

Definitely spray cans!  I'm not sure why I was thinking shellac or vanish should be avoided.  I think I read that comment on a tesla coil building site. Thanks Chobbs for the insight. I do like the spray shellac.

I saw a video on YT posted by a guy winding a rather large secondary for a Tesla coil when researching for ideas for my coil winder.  He used some sort of lacquer or varnish (not exactly sure what) that he applied with a credit card.  Looked rather nice.  I think the "candy apple" look might have a cool retro appeal, though I think I want to go for smooth myself.

Bcourson, what did you end up using, and has it worked well?
