M77 spray

[Norman Ellis]

LHS no longer carries 3M 77; their distributor now
sends them "3M Spray Adhesive for Styrofoam" 3M
catalog no. 6070.  I was looking for something that
would permit gluing foam blocks together and be
non-resistant to cutting wire. This stuff does it.
Also works as a general purpose contact cement to bond
anything to anything.
