ozonation

[lance lafargue]

John,
I don't know how nice this piano is and if you'd want to do this, I did not
read all of the earlier posts, but there is a product called CRC that I've
put on older pianos and flood damaged pianos that closes the pours of the
metal to stop the oxidation process.  It smells like Liquid Wrench, but
seems to work.  I would not put it near the block, but I have put it on the
speaking and lower sections of strings.  I would do the Dampp Chaser, then
CRC if needed later.
