Epoxy repair/fill small hole

[noercarr]

I epoxied a VERY rustic walnut slab. I'd be lying if I said I did it in less than 10 separate pours, this thing had a crack that ran 46" out the top when filling from the side. I'd mix a small batch, pour in in the cracks till "full" and come back the next morning to find it "empty" again. After damming, burn in sticks and what I'd call a pretty successful seal coat, I finally just poured the flood. Went great except for 2 pin holes that were persistent bubbles I popped for about an hour or two, then overnight became a hole.

What are my options here, besides another flood coat?

You could plug it with 5 min clear epoxy and a toothpick to below the surface and then
topcoat again.

you think it would stick, unsanded? I'm really trying to avoid another topcoat

I would stain the pick to match, the key would to make many tries and end up with wood at surface, then small dollop of 5 min clear.
