I have been watching the debate between hide glue and silicone adhesive.
I am reminded of gasket sealers.  When I was young, the choices were
gasket shellac (a messy and disgusting substance) or the various
versions of Permatex Form-A-Gasket.  Permatex was only slightly better
than shellac.

When silicone sealant came around in the late 1960s I tried it and
never looked back.  I found a substance which would prevent oil leaks in
British motorcycles -- this was unheard of!  Over the years I have used
it for many things, including wire insulation and PC board shock mounts.
It tends to be a bit corrosive to copper, but not excessive.

I was taught to use hot glue by such people as the late Rice Berkshire
and George Carr, as well as Arthur Bursen.  I learned my lessons well.
I tend to be an experimenter and I rebuilt my Ampico A Franklin upright
some 30 years ago using hot glue to cover the pneumatics and silicone
to stick the pneumatics to the wind chest.

I had to repair one which had been damaged recently.  A hot knife easily
removed the silicone which, by the way, was in excellent condition.
A sharp knife easily removed the residue.  The pneumatic was repaired
and reinstalled with no problems and performs well.

I suspect that there will always be the innovators and the "not
invented here" people.  I support your right to choice as well as mine.
Please don't tell me I am wrong unless you have some data to back it
up.  I submit 30 years of excellent performance on an Ampico A Franklin
as my documentation.

Best to all of you.
