This is a remarkable treatment with dramatic results. We did the CA glue treatment to my 1902 Steinway Model A which had a lot of false beating in the tenor and middle registers. My technician wears magnifying goggles while he does this so to see the cracks more clearly. With the goggles on you can see cracks that are almost invisible to the naked eye. He also uses a very fine extension pipe on the end of the CA glue container to lay in the glue precisely. We used a paper towel to soak up the excess glue if any, and a wire brush across the bridge pins removes any excess we missed afterwards. We did both the front and back of the bridge. Most of the falseness is now gone from this instrument. Kurt Matthies "Helper"
