Yes, I will fill all the porous rears of bone. I have seen where you put talc as a filler and then super glue on top. It sinks in and becomes solid.Hi P P.08 -Thin CA glue will fill the voids. Apply carefully, I use magnification. Overfill a tad, it sinks into the voids so might take a few applications. Carefully sand smooth after it dries, start at 220/320 grit wrapped around a flat stick and go up the grits from there.
ETA forgot to mention, you said a spot, I'd be inclined to go all the way around.
