Refinishing - Stripping & Stain Uneveness

[pianolac]

Gordon,
Please accept my apology for inadvertantly giving the wrong impression.  It
was never my intention to assert that no sanding is necessary after
stripping with Dyna 2.  It does such a good job of removing old coating and
stain, that very little sanding is required, but that sanding (in the
PianoLac system) is part and parcel of the pore filling/pore filler removal
operation.   I've done dozens of pianos using this method, and never sanded
through the veneer.  I'm careful.

Never had much luck bleaching.  Bleach tends to soak through the veneer and
lift it.  Maybe I didn't spend enough time figuring out the minimum amount
of bleach to use.  I was always able to compensate for differing natural
veneer color by staining and toning.
