Peeling paint on Samick plate

[Geoff Sykes]

Hi Mark --
 
I can't see any evidence of structural damage. While the piano had not been
tuned since it was purchased, (-41c), it appeared stable after a pitch raise
and fine tuning. I'm guessing that the plate was, as you suggest,
contaminated. The paint is very thick, but not brittle, and is coming up as
a stiff sheet. Like in the course of drying and possibly shrinking it just
sort of pulled away from the plate.
 
We have a couple of excellent finish and touch-up guys here in Los Angeles.
I have contacted them but have not heard back yet. I'll post their responses
when they come in.
 
Thanks --

Hi Geoff -
 
I have certainly never seen anything like it, and while it is difficult to
determine very much from the photo, I am having a hard time imagining it
happen unless:
1.  There was/is some structural movement (expansion/contraction/cracking)
of the plate along the finish "fault line".  We've had expanding action
brackets, are we now moving into expanding plates? ;-)
2.  There was a major contaminant inbedded in the plate along this line,
causing the finish to 'float' above it as an unattached film, and finally
cracking after enough temperature changes. 
 
I would certainly seek a possible warranty repair, and absent that, it will
be very difficult to make this disappear, although it could certainly be
greatly minimized.  What kind of finish do you think it is?  
 
As always, before any repair ensues, I would try to first ascertain the
cause.  If not structural, this would be a good situation to call in a
first-rate touch-up artist.

Greetings all --
 
I was called to work on a Bernhard Steiner piano today. Bernhard Steiner is
currently owned by Samick. I think the piano was made in 2001 but the
decoding of the serial number doesn't make sense, (KJKJG0141). Wouldn't KJKJ
be 1011/1011? Anyway, attached is a photo of the plate showing the left side
right under the music desk. Notice that the paint is peeling up in a very
large and thick sheet across the curve of the plate. Has anyone else ever
seen this? What did you do to correct, or fix, the problem. I'm thinking
that if we can't get the store that sold it, (rumored to be out of
business), or Samick to cover it under warranty then perhaps some never-fail
CA glue. But... I'm open to suggestions.
