I have a customer with a new Steinway grand. The keys have a pronounced sharp edge right at the front corners. It seems easy enough to file them smooth but I'd like to buff them up afterward. I have no experience with acrylic tops and I'm not sure what compound/wheel/speed combination will do a good job and not burn or damage what seems to be a fairly soft material. Anyone have any suggestions or should I just buy a set of tops and experiment? Thanks! ---Dave Doremus New Orleans
