Ferris See-Thru Mold Compound

An industry favorite for decades, this material makes an excellent mold of the original article. Mold compound forms a transparent rubbery substance when backed at 350° F, making it very easy to see the model when cutting apart the mold. One quart makes 10-14 molds. See-Thru mold compound is typical of its kind of material in that the resulting mold is very flexible and tears very easily. It recommended that relief cuts are not made into molds made from See-Thru compound.
