Hey, Gary, that video is gold! If it works on a guitar, it should work on a piano too. many good hints on the video. But for a larger area, trying to match the color, draw grain/scratch, and topcoat, man that would be like walking on water. If anybody can do that and make it nearly disappear, let me know. Or teach a class. Other than using lacquer to fix a larger area in a wood color, I've not had much luck with polyester repair of that type. I've used water-thin CA glue, but it often still leaves voids which won't disappear. I've also used the GlueBoost products with limited success on high gloss black poly. Using real polyester for black poly repair works better, at least for me. Konig material.
