I'd stay away from brush-on varnish because unless you're really good at that (which I am not) it tends to get gloppy, sticky, messy, and as you rotate it, it picks up dust, and for me my hair is real long so that gets in there too.
I prefer the spray Schellac in a few coats to keep the coil happy.
On the tensioning the wire bit, just wait until its chilly outside then go back and tighten the winding. I do that when it gets chilly.

Coatings are used for isolation nor are they needed. They are only used for mechanical protection against dings, etc...

Some use miniWax, some shellac, some two-part epoxy, some use tape, and some use none at all.

Rich Hull, master of the Magnifier, never used protection around his secondaries.
