Cyanoacrylate

Cyanoacrylate glue--sometimes known as super glue or CA glue--is a lightweight, strong, fast curing adhesive that works best on porous materials like wood and cardboard. It comes in a variety of consistencies, depending on how runny you need it an whether or not you need to fill gaps. Because it can make a mess on your model and on your table--and even stick your fingers together--be sure to have some cyanoacrylate debonder on hand to free yourself.  And conversely, you can use cyanoacrylate accelerator to stop CA glue from running and cure almost instantly.
