The Dallas model has large hollow spaces inside the hind legs. Fill in the hollow with a ball of aluminium foil, paper, Styrofoam or any other light material and glue into place. Any sort of glue that will stick to the plastic and filler material will do. Hot glue is fast, but any sort of craft adhesive will work. Once the filler is in place the hollow can be filled with epoxy. Or for the creatively frugal, fill the hollow with foil, and then apply Bondo. Once the Bondo has set, spread a thin layer of epoxy over the base layers of bondo and foil. Bondo is automotive body filler, and comes in two parts, goo, and hardener. To use mix a small bit of hardner into the goo, mix well and use fast. The advantage of using Bondo is that when it is freshly mixed, it flows, and can be used to fill in small cracks and crevices. Look for it in the automotive section of any store that carries car parts. Bondo is cheap, a gallon can costs about $12.00, and sets up in about 10 minutes. It also is smelly, and somewhat toxic. Follow the directions. Any of the epoxy resins will have a harder final surface and will sand to a smoother final surface. |

The next step requires some minimal sculpting. There are several brands of epoxy putties on the market. Magic Sculpt, Apoxie, Martin Carbone putty. There is even plumbers putty that sets up in about 3 minutes avaliable from your local hardware store. Which material is used is not important. The basic idea is to use the epoxy to create a layer of detail over the existing surface of the model.
Add a thin layer of epoxy over the fill inside the legs. Keep this layer thin, as epoxy is heavy and will change the center of gravity of the model if too much is used high on the body.
