    Cyanoacrylate Adhesive, or Cyano-Acrylate Adhesive (CAA), more commonly
known as "Super Glue".  There are different viscosities -- very thin,
medium, and gap-filling, and also
accelerators, or "kickers" to make it set up faster.  Moisture also makes it
set up quickly, so storage is somewhat of a problem.  The caps have to be
replaced immediately, especially in humid climates.
    Word on the tech
grapevine is that most superglues in hardware and grocery stores are past
their shelf life and it's better to buy them in hobby stores (not
necessarily Michael's or Hobby Lobby, but model airplane- and model
railroad -type hobby stores.
    Do not buy in large quantity unless you're
treating many many pinblocks.  The stuff sets up into one solid mass too
easily if the bottle isn't really tightly sealed.
    Also get a bottle of debonder for those accidental spills or unintended
fastenings of two fingers together.  Acetone also works - chemical supply
house acetone being better than fingernail polish remover.
