About a year ago I was reading RCM&E (model flying magazine), and a modeller building large scale gliders was using a cyano called 'Liquid Weld', and swore by the stuff. I thought I would try it, a two year shelf life and industrial strength is claimed, and it is only available in the UK. Have to say it is excellent stuff and the best cyano I have used. I store it in the fridge, (strange look from SWMBO), and after a year it is still going strong. For applications which need a longer setting time I tend to use 'SLO-ZAP' by Zap, it is a thick CA which is slow cure, high strength, and gap filling, particularly useful if your carefully crafted joint isn't quite 100%. Neither of these products is cheap, but you do tend to get what you pay for. Personally I avoid cyano and epoxy from Poundland.
Just my ten penn'orth on the subject of 'stickum', as most modellers will have their own personal preferences.
