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. --David Nereson, RPT
