I have never done anything to a cork grip. Now I have a new rod and the cork looks so new....I sense I want to treat it or seal it with something before I fish with it. Would someone please tell me what to do? Careful now....

I have been told or read so many different things. I do not wish to just pick a method and do it to my new rod.....and then be unhappy with the results.

Do nothing....let it wear in like a good old pipe or coffee cup....

Treat it with a cork sealer like something from Trondak I think I read

Rub it with Ture Oil....a gun oil...

Rub "Guberod Rod Varnish" into it. ( I have never heard of Guberod Rod "Varnish". Perhaps there is one.
I have not searched as am camping and no internet. So this a quickie question. I know there is a
Guberod "Rod Cement" and a Guberod Rod "Finish". If Guberod has a rod varnish then how about
any old varnish?

I am wondering about just smearing it with soy sauce.

Any suggestions would be helpful and appreciated. My goal is just to coat/treat it with something before I take it out fishing in water, mud, brush, rain...etc. I just feel the desire to put something on this brand new looking cork before I use the rod.
