I find it useful for instruments where I am feeling my way along and/or
where it is clear that the situation is one in which the instrument will be
getting heavy enough use that the hammers will harden up under use and need
some initial support while that is happening...like practice rooms.

Also, for those starting out with learning hardening techniques, it is very
forgiving, generally being fairly easy to wash out when one blows it.

Glad to be of help.

Best.

Horace
