I'm in the sanding stage of a gunstock. Got to wondering if anybody ever tried a product called wood restorer for the initial sealing of one. It is a thin liquid that you slop onto wood that has gotten punky, and it penetrates and hardens, giving strength and water-resistance to the wood. I'm thinking it might make a good sealer for walnut. Paint it on inside and out, then sand it off the surface when dry and start applying the oil.
