If possible, use glues that can be reversed or removed with little effect on the main materials. Food Grade forms of this putty are available, and most types will withstand up to 600 F, making them useful for metal casting as well as liquid polymer clay, polymer clay, paper, resin, epoxy resin, gelatin, chocolate, and sugar molds. Another product from the same company is Delight Air Dry Clay This light, marshmallow-like paste takes detail beautifully and blends with a damp paintbrush. Although many modelers assume epoxy resin is the only way to mimic water effects for large-scale scenes, there are several easier methods which can be more realistic for items such as miniature ponds, waterfalls, and other purposes.

Model horse enthusiasts and dollhouse miniaturists may use it to change the pose or shape of cast resin sculpts. Both materials give off some gasses, so they should never be left unfinished. Plywood structures are lighter and can be built to be dismantled or added on to at a later date. The decision of which to use is personal. Laminate several pieces together if you want a stiff construction.
