   One thing I learned about this is that not every casting material 
will behave the same way during casting and curing.  Resin-based parts 
typically retain the shape in which they're made, but some quick-cure 
casting compounds will warp to an amazing degree as they cure.

   In other words, buying a casting kit expecting to use some other 
casting material is not necesssarily a good idea.
