As posted before, I'd go with Liquid Tape. Use a lot. Wrap it before it drys with electrical tape and then coat that.

Don’t use silicone sealant. The acid in it will cause the copper to corrode. As said, liquid tape would be the best solution.
Yes, most all low cost silicon sealers have that peculiar citric acid smell which indicates that product is combining with humidity from the atmosphere to form an organic acid catalyst to kick off the cure. I haven't seen that be a problem with corrosion - but the possibility is real.

I don't know about the liquid electrical tape & have never used it. If it has that sharp vinegary smell characteristic of the inexpensive silicons then I personally wouldn't use it either.

I do know a little about silicon sealants. I learned about them back when I was doing instrument design. Some industries use non-acid silicons sealants in a tube that work just like gasket sealers but are more commonly used in firearms, optics, aviation, and aero-space. They have no smell when curing. They are called "non-outgassng" or "non-acid curing" & the lack of odor makes them easy to identify. More adhesive, tougher, and longer lasting than their smelly cousins. More expensive, though....about 10x.

An example is Dow Corning 3145 in grey or clear. It's sold online.
