I have some black walnut with live edges. Iím planning on keeping the live edge on one side. The wood is air-dried, so thereís a really nice contrast between the white sapwood and the darker heartwood. I would like to preserve that.

The professionals often recommend using BLO and garnet shellac under Waterlox. Hereís my newbie question: will the BLO and shellac affect the color of the sapwood? If so, should I skip the BLO/shellac and just use the Waterlox by itself?

Thanks for any advice!
