Epoxy can usually be found in the plumbing section of your local hardware store, Lowes, or Home Depot. Even Wal-Mart carries epoxy.
Epoxy usually comes in two different forms. The first is almost like clay or play-doh. It will be in an stick consisting of an outer layer, usually blue or grey, and an inner core. Then you just cut of a little bit and mix with your hands until uniform in color. As far as I know most putty is inert and safe for use in the reef auqarium but I usually will opt for a brand that specifically mentions "for potable water use" or "for drinking water use".
The other type of epoxy is a two-part liquid or gel substance. I have heard of people using it in their reef aquarium but I have never tried it before. Maybe someone with more experience with this stuff can chime in.
