I just picked up this Steinway upright, and found rather thick, gray paint all over thre back posts and soundboard. Gray sandable primer is, I believe rather soft ( = sound absorbing. ) If I have time, I'll get a bunch of carbon filters for my gas-mask, and try to blast it off with lacquer thinner in my spray gun, with a  bottle brush to get behind the posts.     Peace,     G <o:p></o:p> </div> <o:p></o:p> </div> </body> </html>
