How to sand epoxy flush, but not surrounding wood >320 grit?

Thanks for the info. As the void went all the way through, I can test with the finish on the inside of the piece with it being sanded and with the OSMO to see how it looks. This was just a practice project to work on dovetails, so if it doesn't turn out flawless, I can chalk it up as a learning opportunity.

FWIW-I know from multiple projects that WaterLox will fill and eliminate 220 sanding marks in epoxy. BTW-scraping is much faster and easier for leveling epoxy overfills than sanding.
