High gloss polyester finishes such as those found on Yamaha pianos, as well as many European and Asian instruments, can be made to look almost perfect. That perfection makes an accidental scratch or chip quite upsetting. Trying to fix high gloss polyester with normal finish repair materials and techniques, no matter how good the technician is, will never be satisfactory. Even if the repair looks acceptable when finished, it will likely degenerate within weeks or months because the repair materials will not respond to environmental changes the same way as the original finish materials react.
We pioneered efficient and permanent in-home polyester repair over 25 years ago. We went to Germany to find the materials, and spent several years developing a system that works. We have taught our technique to technicians across the United States and Canada. Nobody doing polyester repairs today has more experience than we do. So if it is a small scratch, a dent from a fallen lamp, a big chunk from moving, or a desire to have your piano’s finish brought back to the full brilliance it had in the showroom, we are the safe, reliable choice.
