I'm not impressed with the VS stuff.   Anyone want to buy my bottle?

Well, there was some talk on  here a while ago about the use of a liquid called VS Profelt for exactly that purpose. It seems to have been very successful for some, but no-one knows yet how long the effect lasts.  It's only useful, though, if the bushing is COMPRESSED rather than all worn away. It can decompress the felt fibres, but not replaced them if they've been worn away.  It's used with cauls.

I guess the black stuff could be a residue from some previously used lubricant?

Best,

David.

>Just left a customers piano that would benefit from new key bushings.  However, on the way to lunch I thought the ones i looked at did not appear to be overly worn yet they are loose and >make some side to side noise.  My question is:  is there anyway to swell the bushing and use an appropriate sized caul instead of completely rebushing the entire set?  Just wondering out loud >so please don't beat me up. :)
