A word of caution : DON'T use polyester!
I did coat a secondary with polyester-resin and it does look really
nice but the coating has not adhered at all to the wire and it
is so brittle that a weak shock will make the coating shatter..
I'd say that the coating has to be "elastic" - so it might be possible
to use polyester-resin with an approprite additive that'll make it
more elastic but I wouldn't count on it..
I'll test epoxy for the next secondary..
