>Who out there has had experience in polyester repair?

Dear Sy,

As former National Service Manager for Samick in Canada, I personally did a
great deal of polyester repair and taught the techniques to our dealers and
their technicians.  My advice to you is to skip using the factory material
and use only the German Konig polyester repair kit.  There is less guess
work with hardener/resin ratio, has a longer shelf life, can repair every
color with the exception of white and the repairs can usually be done in a
single service appointment (the material cures to a workable hardness
within about 1/2 hour).

I feel the same way.  For a successful repair, great care has to be taken
at each step of the process.  The repair area must by properly prepared and
feathered, the material must be accurately measured and mixed and the cured
patch must be carefully levelled, sanded and polished without altering the
plane of the 'mirror's' surface.  I don't sell pianos but offering this
service to the local dealers keeps my foot in the door for more satisfying
work in the future.

If you or anyone else on the list would like some further advice on these
techniques, I would be pleased to oblige.

Best regards,
