Michael, The Archaic said: "Impact Adhesive" is available in both large =
and small quantities - in large
cans and small tubes. It was developed to stick laminates to a sub =
structure
as in motorhomes and kitchen work surfaces. One manufacturer is Bostik - =
I'm
sure if you google  <Bostik/adhesives>  it will find them. The object of
this adhesive is that when both surfaces are thinly coated and allowed =
to
become "touch dry" they will bond on impact with each other. You only =
have
ONE chance at this, for the union is so very strong. The glue is fairly =
thin
from the tube which allows the "smearing" action I described to coat =
both
surfaces thinly and evenly. Good Luck!

Michael,
On this side of The Roaring 40's, we call that Contact Cement. Yes, it =
does what you say. However, the damned stuff breaks down after a while =
and looses it's bonding! For years, I've been using a gentleman who uses =
contact cement to glue on key tops. Since I've been in the biz for 33 =
years, I'm seeing the ramifications of the use of contact cement. The =
last one, was a key top job that he did 6 years ago. All are starting to =
come off! Yikes! The customer is NOT HAPPY! This is why I've started =
doing my own keytops, using PVC-E, which he refuses to use."Takes Too =
Much Time", says he! Yes, it does take waaaay more time when using =
PVC-E, but, hopefully, we'll get a lot more longevity. IMO, Contact =
Cement/Impact Glue, has no place in a piano. (period)
