Greetings, I've had some real success using VS Profelt when re-sizing key bushings with warmed brass cauls. I also use it on whippen felt and it really reduces the indentation created by the capstan. Generally the hammers are raised almost to where they need to be without a lot of capstan turning. A recent Tech letter from Pianotek said something about fabric relaxers used in the garment and dry cleaning industry being part of the recipe. It made sense when I read it, but I don't remember the details and seem to have discarded the email.
