New be question.. I am thinking of casting a MDF plug. It is a fuselage for a model airplane.. I have been looking on the net and other people have set the plug in a parting board. built up some sides to the parting board.. Then used a gel coat and then a epoxy mix to cast there mould's.. Do you have anything like this system. Or will the UNI mould making system do the same thing?  I cant see it being as ridged as a solid epoxy mould..
