Is it possible to get consecutive smooth layers without paper?
I used to have to manufacture a small Transformer it's been awhile and I've lost some things. The one I did was ferrite about 3/4" ID. It was very hard to get a tight good looking wrap. Plus they wanted the coils to lay on black tape. When it was done we painted the hole thing in Plastic insulation.
Some things are just as they are and a tight rap is what your looking for. If you insulate the outside you'll never see it. You really just want a stable Q.
Edit: oops, I thought you were winding Toroids or Transformers.
