Default Varnish on top of oil, for high dielectric strength and looks

Hi folks,

I'm intrigued. I recently put two coats of linseed oil onto a piece of driftwood bark. After a week, I varnished over the oil with marine grade gloss varnish and the finish is deep, lustrous and stunning.

I am going to try the same thing but this time, I'll immerse a pulse transformer in transformer oil (which is a very light grade), let the excess drip out for a few days and then attempt to overcoat with the same varnish.

You might think that wood is a very different medium to wire, and indeed it is.
But what makes me think this possible is that this is litz wire, with a very high capillarity.

Let's see. Could be very useful indeed.
