There was no stain put on the wood, just the natural beauty was brought out with some satin finish poly.
Instead of the box top, I chose to use the (soul) sister board from the one that supplied the doors for the top.
The mixing of the resin/hardener produces bubbles, without much way of avoiding them. I got a few of them popped at the surface with a toothpick, but sub-surface bubbles required the use of my oscillating palm sander. I got some of them, but bubbles remained. Oh well, the boards are not perfect, and neither should it.
The hatch marks from the milling came through beautifully, and after 4 coats of satin poly finish, the doors are ready for hinges!
