I let the slab sit all clamped down to the sawhorses for well over a week, nearly two, and injected all the seams with copious amounts of wood glue. There was same twisting and racking as they dried all the way out so now I have to address the glue blobs on the end. I decided the easiest and quickest way would be to square up and trim at least a quarter inch off each end.
Then I bring it back inside and hit it with a coat of whitewash.
After that is dry I hit it with a second coat. Meow I will let this dry overnight and the next step is a coat of polyurethane to lock the whitewash in so I can do my dark glazing over it, and then wipe it back so it only stays in the low spots.
