As Ron said, sunlight damages the piano, regardless of the color of the finish. The YC has a poly finish, and even though the finish itself cannot be harmed, the wood underneath will contract and expand, which will crack the poly. If the piano has to stay in the window, recommend to the customer to get window filters by 3M, or other companies. It is a film that is applied to the window, that allows in light, but removes the ultra violet rays that create heat. It will not only save the piano, but greatly reduce the need for A/C in the summer, and the glare of the sun.

List I got a question yesterday I didn't have an answer for. The owner of the piano asked me if sunlight would damage the finish on her piano. Normally, I inform the client that long-term exposure to sunlight will fade the finish and/or leave a milky white patina to the wood. However, this piano is white. I don't know if the finish is lacquer or polyester. It was a Young Chang GP150. Didn't know what to say. Will sunlight damage a white finish, too? Or is that the only advantage to having a white piano? Other than boldly announcing to the world: "I have no taste in decorating!"
