I made an end-grain cutting board and thought I had all the little voids filled with glue (Tite Bond 3) and sawdust. I tossed it into a container of mineral oil to soak for a while. I pulled it out yesterday (It looks great!) but I now see a few more holes between some pieces that I missed filling.

What can I do now? With the board being oiled already, will TB3 and sawdust stick in the holes well enough? CA and sawdust better? Any other options or tricks on how I can fix this?

Thanks!
