More like "gouges left from ripping tape off of delicate veneer" filling. The Koa parts have actual pores, though. Thankfully the neck is level and does not need this.
Here is the state after a seal coat of shellac on top of the boiled linseed oil; one coat of epoxy smeared into the--uh--low spots, dried, and scraped and sanded back; and a second coat of epoxy applied. Not shown: my feet covered in epoxy shavings after scraping the first coat. It's such a shame to see that wet shine knocked down, but it has to be done!
