John,

Kluge doesn't use hide glue.  I believe that it is some sort of heat
activated glue that is pre-applied to the felt.  I have no idea what the
formula is.

Another thought.  What formula of McLube are you using?  The old 1725
formula works well but the new *environmentally friendly* 1725L tends to
gum up after a while.  I've had this happen to me a few times.  I was
talking to Rick Baldassin and he mentioned that he sent all his 1725L back
and was trying to get the old stuff again.  I still have some of the
original formula so I have not tried to exchange the 1725L.  Has anyone out
there done this?
