Guys, I've got a few rods that are several years old and the cork handles are starting to form holes. Looks like the softer part of the cork is coming out. Its not that bad and I've still been using these rods anyway. My question, is there something I could fill all the holes in the cork and sand it down? Like a filler.
I've seen the local repair shop in town do something, but I would rather not take it to them. Who know when I'll get them back.
Any advice is greatly appreciated.

Thanks!
