Michael's does carry it. At least the one in my area does. However, it is not in the place where it seems it should be. My hubby used to work there and he took me straight to the glue and modge podge section where it used to be. They moved it. Spent 20 minutes looking around for the stuff and finally found it. It is the same type that Gweede mentioned, mold builder. I use it for corpsing my pumpkins. If you go back, you might want to ask someone. Usually somewhere among the employees there is one person who has familiarity with the products.
