Cork filler for handle?

[saflyfish]

I have two top end rods whose cork is not great.There are quite a few holes in the cork.Is there any kind of filler i can use?

Suggestions please?

Cork dust mixed with a non-water soluble glue always worked for me or Plastic Wood which you can sand after it dries.

I've built quite a few handles and have changed my mind on "filling" the holes. I no longer do it prefering the natural look rather than the filled and sanded. Holes in the cork are the natural look and I now prefer it to the filled.
