Thank for everyone’s reply and insight. I lightly sanded down the last coat and wiped it down with Mineral Spirits. No damage to the engraving. I hit it lightly with a heat gun and it seems to be dry. So, today I will give it a couple light coats of spray Poly and see how it goes. The drying of the engraving isn’t the big problem as much as the small area around the outside of the burn areas. After the first coat of wipe on poly, the finish had what I would call an outer glow of tacky poly outside the burn areas.
