These are 100% done with a 3D cut path on the CNC. Even the tiniest amount of sanding would be evident or erase details. I soak with Rubio Monocoat, then with an air nozzle in one hand to remove excess in the tight areas and fresh small rags in the other, I remove most of it. I work a panel or two at a time. Even with that, it brings out nice detail in the Sapele and seals it up.?
