really nice veneer you've used there. And I like the walnut stain.
Did you get the Birchwood Casey sanding sealer/filler to use before the Tru-Oil goes on? I'd recommend it, using two coats and then sanding that before applying the Tru-Oil. It really helps stop the first coats of Tru-Oil sink in to the wood.
But I'd finish the rest of the body with stain or any other finish you plan to apply before putting any Tru-Oil on, so you can apply it over the whole body at once.
