New finish on old fiberglass rod.

[TWFairweather]

I have a brand new Wright & McGill fiberglass rod, it's from the 50s or 60s, the Rod has never been used but it seems what finish was there isn't much anymore. Whatever they used must have been very thin, even around the wraps you can hardly see anything.

Maybe they used shellac, there's no cracking or anything. Is there anything I can put on, I'm mostly want it so the line is smoother when it hits the rod or if the rod rubs on something that may scratch the glass.

I was kinda thinking a few coats of boiled linseed oil may work.
