Above I have already gave the pic of the coil, I did without lugs. No need.
The fish paper I have is rigid as it is (as a product it is designed to be rigid and resist mechanical stress, it even has some mica in it just for that) but then I did two-ply glued together, which I then rolled and glued, and then when it dried, put it on a cylinder (somehow it fitted exactly to an aluminum cap I had which was 1"), heated it up a bit with a heat gun and left to cool, then took it off - it is a practically ideal cylinder now. Very rigid. In fact way more rigid than the original coil. Plus I think non-palatable to rodents as it has mica. (I think the wax is the substance the rodents were after, they love eating candles).

I will probably get a spray lacquer as you suggested. I do not know if it is safe for enamel but as it dries very fast it probably won't damage it.

Actually there was another though - I secured the winding with fabric glue (dries clear) and I though, why not using it for this? I could just spread it thinly all over, inside and outside, and it will waterproof it. Won't it? (I mean, moisture-proof )
