This 2006 model 620 developed an issue with its clear coat, which began to soften and grow sticky after many years. As the finish was long out of warranty, the only choice was to have it refinished. Studio California matched the color and shading of the original Amber Fireglo, and topped it off with our usual 8-coat hand-buffed catalyzing clear coat finish. Guitars finished with this clear coat a full 15 years ago still look as though they were freshly-clear coated, and still wet. The stuff isn't cheap, but in many hundreds of finishes over a decade and a half, not one has failed that we're aware of.
