I second the Zap-A-Gap idea, also Slo-Zap is very good, and some stuff with a red cap I got off ModelPower at llanberis is good stuff too, even though the nozzle has broken off and I now have to use a toothpick.
I will never buy a bottle of thin cyano again, it's stuck me to other parts of me far too many times, and has ruined many a good model.
I did once stick both hands together, and not being one to go to hospital and not having heard of superglue debonder, I decided to remove the hands from each other with a X-Acto blade between my teeth....
