I recently purchased the two part to use on some frags as a trial but I haven't yet used it. Previously, I've been using the Zeo Speed-glue (like cement) and though it's a pain to work with, I would say I'm successful 3 out of 4 tries. Golds sells it. It is a powder that you need to mix (mix it really dry) and then you have about 3-5 seconds once you put the clump of it in the water. If you are fast, then you have a really good stick. If not, then it comes out easily enough as a lump of concrete.
