I just reshaped a neck heel from fenderish shape to a flat across shape in order to fit a certain neck pocket. It required removing 1/8 inch of wood in some spots. Its a standard maple/rosewood neck with satin finish and the only things that got touched during sanding were the 3 flat sides of the neck heel (had to shave maybe a millimeter off the sides for width issues.) The final fit came out wonderful. So how do i refinish this and seal that wood?
