I don't know of a gray one. The best is Armaflex and it is black.
They sell their own contact adhesive. Here is a reference:

You know that gray foam rubber/styrofoam stuff they sell to
insulate copper pipes? Does anyone know a good glue that would
work to seal this stuff to itself? Something that sort of
"melts" the foam slightly to form a "welded" bond would be best.
(I think that's the sort of thing that happened with plastic
models and model glue I used as a kid.)
