Chris,
Aquamend sounds right. I think lowes and HD only carry two kinds. One has metal in it and the other one does not. Just remember to lower the water line in your skimmer cause the epoxy from lowes has a lot more oils in it and will make your skimmer go crazy. If you are only gluing in one frag here and there you will be okay, but if you get a good amount of frags and want to glue in like 6 I would advise getting the stuff from the LFS or your skimmer will be messed up for days and you will need to clean the oils from the inside.
