Dick, you have just hit one of my buttons. Silicone IS a no-no around a piano. Silicone is not a lubricant but a strain reliever. It has a nasty habit of traveling all over the place, like dropping a barrel of BBs from the roof of a warehouse. They will go everywhere. If there is an interaction between to object, like tuning pins and pin block, like keytops and key stick, silicone will get in between and relieve the strain. When it gets under the finish it is a devil to refinish. When it gets into the pib block it will have to be replaced. There are places for silicone, but I cannot think of any, especailly around a piano. Newton
