My experience with the stuff (I have used a lot of the stuff).
If you attach it and then move it ever so slightly after the first 3 seconds, odds are you just ruined the instantaneous chemical bond at which point it becomes a 5 minute wait or longer.
If you use too much, it also tends to not bond fast as well.
It is easy to fracture a joint later (if needed for some reason). I have not experienced any real grief needing to remove a part later for some reason. You need to remember, model glue melts and welds, and crazy glue is just a chemical bonding agent. The parts were never melted and welded as is the case with model glue.
Great for gluing on a small part on a painted surface. Because it glues anything to anything. If the paint is set and well adhered, it is not a problem to glue to a painted surface. Remenber though, a sharp force can fracture the bond.
Of course you will need it for PE metal parts and cast resin as they are not model plastic. It works like liguid model glue ie it will seep through cracks creases and under stuff. Be aware of where your fingers are.
You can get stuff that will excelerate the bonding of even these supposedly instant glues. I have not had a lot of enjoyment using the stuff though.
Yes, have debonding solution handy. But even more so, work over a glass surface, trust me on that one. It's permanent on almost anything else that gets drops on.
I have never seen it actually glue some types of plastic. Forget trying it on plastic like one piece tracks, the stuff is just not suitable. I have glued and clamped that sort of plastic and a day later it is like it had never been glued at all. The stuff just doesn't like soft waxy feeling types of plastic.
