I recall reading somewhere that defects in cork can be filled with a mixture of (something) and the fine cork dust you produce when reaming/sanding handles, etc.

Anyone have a formula and technique that they can recommend?

Thanks.

I use wood glue and add the cork dust till it becomes a thick ( peanut butter consistency) Then push into the holes. Let dry for about 24 hrs and then sand to your likeing.

Thanks for the quick response. I assume you use a good waterproof glue like "TiteBond II" or something like that, correct?

Personally, unless the pits are really bad, I don't bother filling them. From what I have seen, most of the time, filling the pits does not seem to last very long.

Hello Skip
I use a mixture of Rod Bond, cork dust and a very small amount of fine ground dry Titanium Oxide paint pigment. Mix Rod Bond and cork dust to a dry putty. Then mix in the pigment to match the color of the cork. Then press this mixture into the voids using a spatula. Do not smear it around but press it in and remove excess with a cleaned spatula. Firmly wrap with saran wrap or generic plastic wrap (used in Kitchen). Then firmly spiral warp with masking tape. Let cure for 8 to 10 hours (overnight). Then remove the wrapping and sand lightly.
This filler will last as long as the cork grip and is a permanet fix. Looks and feels great. You can apply cork seal after filling and sanding and get more life out of the cork grip.
All the other fillers that I have known will eventually chip out -as they do shrink and become brittle. Rod Bond remains flexible and does not shrink.
It take a little longer than the quick fixes but lasts and looks great.
