I might have missed this but, has anyone tried to use Flex Seal as mold compound. In the adds I see all over television the shill puts it in a cake pan and it comes out solid piece of rubber. I wonder what you'd use as a release agent.

It won't work very well. It is a solvent-based rubber material which will shrink as it dries (hardens). Unless the mold is very thin, the drying process will be very long and the shrinkage will be very noticeable.  RTV rubber mold material hardens by a chemical reaction (not solvent evaporation), so there is no appreciable shrinkage and it will set in thick layers.
