Let's see if I can type it right, it stands for Cyanoacrylic Adhesive and is not an epoxy as epoxy is a 2-part adhesive/glue/cement, the resin and the hardener.
A Hobby Shop is the best place to get it as it seems to be better than what you get at Home Depot, etc. You'll also have a better selection of fast or slow setting, thin and thick. There is also an acellerator that comes in a squirt bottle to make the CA set faster.
When Jerry said "kicks", you might see what looks like smoke coming off the CA. Watch your eyes around that stuff so kind of stay back a little while applying it.

Keep asking the questions.
