In talking to Kevin Cory some years back at a convention, he indicated
that the High Gloss polish will work equally well on satin finish pianos,
but the reverse IS NOT true. So I've been stocking only the one type and it
seems to work fine for both. Don't know if the formulation has changed in
the meantime, but so far, so good.
