The current system:
Packaging peanuts are glued together with hot glue and pour spouts are made out of pink insulation.I have used both drywall mud and plaster and found that plaster is much better for holding the shape.
After the foam is coated with plaster it is buried in play sand and the metal is pour over burning out the foam.
Cleaning the plaster off is a pain. Currently I do it by soaking the piece and working out the plaster with a fine metal tool and a wire brush. I was thinking a pressure washer or sand blaster might work well.
The hot glue sometimes obstructs the profusion of the metal. In this piece one of the rear legs is not getting the metal.
