Patience ..... !!!! I sand the whole blank to about 800 grit. I use the point of a straight pin to remove the white stuff from the divots ... one divot at a time. After I have cleaned out one divot, I dip the point of another pin into a small puddle of thin CA and transfer a tiny droplet to the cleaned divot, sticking the pin point into the divot. I repeat this until the divot is filled with CA. I wait about 15 seconds and spray the filled divot with a little bit of accelerator. I wipe of the excess accelerator, inspect the divot and if it looks filled, I sand the area with 800 grit to smooth the surface of the divot. Then I move on to the next divot and repeat. After I have treated all the divots I can see I resand the whole blank, inspect, go over it with micromesh or finer sandpaper, and polish. It's a painstaking process but worth it in the end if you value the blank.
It is helpful to have the first pin mounted in a pin vise to give you a little leverage cleaning the divots. The second pin develops a growing blob of CA on its tip. When the blob is small it helps pick up and transfer the droplet of CA.
I took a long time typing this with interruptions. I see that two got in ahead of me. I also see that Ed recommends using a needle/pin. I don't find it necessary to allow the CA to cure as long as he says. After using the accelerator and wiping off the excess, I gently sand the divot and surrounding area.
