This guy is The Source for everything to do with finishing.I remembered reading an article he wrote for Fine Woodworking discussing how today's Walnut has a greyer cast than the browner wood of yore. He recommended Amber shellac to bring out the richer brown tones and I just completed the first of several coats (Zinsser Bullseye waxed, diluted 50% to a 1 1/2 pound cut, applied with a pad)on the Walnut veneered 4 Pi's. What a transformation! I keep walking out to the porch just to look at them while they dry.
A classic veneer/finish for a classic speaker. Should be done by the end of my next days off Tuesday and can't wait to show them.
