RE: [TCML] Poly thickness

["Lau, Gary" <Gary.Lau@xxxxxx>]

I'm not convinced that coating a secondary with anything significantly improves it electrically.  Mostly it's to keep the windings from shifting on the form, and to provide a small amount of armor should something bump into it.  And probably most importantly, it just makes the coil look nice and shiny.  No matter what one coats the secondary with, it's still vulnerable to racing sparks if it is overcoupled.
