Since I haven't yet learned how to bring someone else's message into this current post, I'm going to quote a Yamaha technician that gave me the method he uses. Although I'm sure most of his work is probably done on Yamaha's, at the present time, it will probably to other brands. He did say that he doesn't like the plastic/acetone mixture on Renner hammers. I've used it a little and it does brighten up the tone, but I'm not sure it's the best way, especially on Renners. His mixture is: about 1 part lacquer SANDING SEALER to about 7 parts acetone. His comments were: "This should bring the hammers up fast enough to minimize the "Are they done yet" syndrome while allowing you the ability to control how much they come up. If the first application isn't enough, you can do subsequent applications quite easily. This also allows you to needle any that you find too "hot"." I like the plastic mixture in some situations, and I know of others who use it, even on Renners. However, the next time I need to "juice" I'm going to try the above mixture. Hope this helps.
