Cascamite/Extramite
Fresh Cascamite is an excellent adhesive, with some gap-filling properties, though not as good as epoxy in that respect. It's also pretty brittle and won't flex much without cracking.
For me the big drawback of Cascamite is that if any moisture at all as entered the tin, the powder can be 'slaked' but still appear the same. You can spend a lot of time gluing things with this, only to have them come apart later on. In other words, unless it's perfectly fresh, I don't trust it at all. For example, if I open a tin, I won't use it after a few days have gone by, because the atmospheric moisture has probably started to do its work.
The old fashioned 2-part urea formaldehydes like Aerolite or Beetle glue didn't have this problem because the hardener was separate from the 'resin'.
