"Hydrocal"is a brand name of a plaster made by U.S.Gypsum ( supplier). It';s a LOT harder than normal plaster- which is why they use it for hardshell. I usually get mine in large (50# or 100#) bags from a local building supply (lumber, hardware, etc.) yard. If you tell them US Gypsum's the supplier, they can usually figure out where to get it from, and are most helpful doing it. There are a couple of colors- white, grey, Ultracal (even HARDER), etc. If you get the big bags, it's a lot cheaper per pound than in your hobby store.
