I'm referring to the white coating around the antenna.
If I was to route it out my Corsair I would route it through a mast and then back to the fin like the full size Corsair. For more of a scale appearance I would like to strip the shroud off of the antenna leaving the bare metal so that it would look more like the real thing.

I know I would need to coat it with something to keep it from unraveling, but other than that would this be a bad thing to do?

The pictures shows what I am referring to. The green line is the route of the antenna.
