I was quite surprised at how well this worked. A muffler rail on a square I'm working on. Client and I decided to dedicate available funds for more useful parts of the instrument than the muffler rail. But the rest of the belly was looking pretty good, and I didn't really want to put the muffler rail back in its filthy state, including filthy felt.<br><br>Took the rail to the bead blaster with fine bead (175-300-I think), turned air down to 20lbs, shot the bead at a very shallow angle, 5 or 10degrees to the plane of the surface to be cleaned.<br>Gave both the wood and felt quick blasts, didn't protect the leather at all, just didn't aim at it.<br><br>By golly, no early/ late growth erosion whatsoever or visual clue of what I did...and mighty quick it was too. Felt cleaned up nicely as well.<br><br>Waddayanoaboutthat.<br><br>Jim Ialeggio<br><br>-- Jim Ialeggio<br><a href="mailto:jim@grandpianosolutions.com" saprocessedanchor="true"
