Another glue question

[Ed McCullough]

I am changing the shape of some chambers in the comb. The first reason is to change the resonance inside the chambers for the F and the F#, whose valves sometimes vibrate due to resonance. First efforts with thus seem to be successful.
-. I also want to imitate those plugs that Brendan power used to sell for purpose of altering the tone color of higher pitched holes.
-. I have been a sticky putty that some people call sticky tack. See picture. Can some of you experienced geniuses suggest a glue that I can squeeze into that space? A glue that sticks to plastic. A glue that can easily be cut and carved with a small knife point.

My favorite glue is E6000, but this glue dries too hard for easy carving.

Bingo!
          Silicone bathtub caulk sticks to almost anything. It is waterproof. When it is dry it is soft enough to be easily cut with a small knife. It is inexpensive, and I think I have a tube of it hiding among my tools.

Funny you mentioned that stuff.
I just finished trimming out the window in my
shower about fifteen minutes ago, and I'm trying
to get stuff off my fingers as we speak.
