The trough will need at least 24 hours to cure enough to unmold. When you can't scratch the surface with a fingernail, it's ready. Remove all the fasteners and take off the bottom panel. Then remove the outside walls, popping the boards free of the paraffin with a garden trowel. Push the walls of the inside form toward the center so they collapse inward on themselves.
