For more than 20 years I have made myself available to Steinway & Sons, when they had questions that were up my alley. So, when I had a loudspeaker design client who was willing to pay, I asked Steinway's outside contractor for special finishes (such as a grand piano in high-gloss Danube Blue Polyester) to do the final finishes on the Richlite cabinets. The front panel perimeters however, got seven hand-rubbed coats of violin varnish. The rear panels, also Richlite, are held on by Silicon-Bronze boat-building screws. Gotta Luvvit. BTW, it's my LS/5.25.
