I am in the process of putting together a new coil and was planning on
using polyurethane to coat the secondary. Is this a good coating
material or not? I was planning on coating a portion of the sec form and
then winding the wire over the wet coat of poly. Then I could coat over
the top. Another main factor in this is cost (like ~$0). I already have
lots of polyurethane from doing woodworking. Comments on polyurethane as
a secondary coating?

Tristan,
I used polyurethane (oil based) on both of my coils. Works great and it is
durable. The large coil uses a pvc form so I applied several coats on the
form first, then let it dry then layed on the wire then applied several more
coats. These were wound on a lathe and the polyurethane was applied and
allowed to dry with the lathe turning to avoid sagging and drips. I would
let the base coats dry first. If you try to wind the wire on when it is wet,
I think you will end up with a big mess. I don't really see any advantages
to doing it that way.
