I just finished a similar (fir) slab and I have to go with Charlie and would recommend a simple ‘knife-grade’ black epoxy – stay away from using a clear epoxy . It somehow makes the void look like a flaw. The black epoxy does not distract from the piece. Emphasize the grain & character of the wood… I would sand VERY carefully and thoroughly – at least to 600 gr, followed by several coats of Deft Danish Oil & 2-3 coats of a good paste wax. Good Luck. Please let us see some progress pics.
