Forced by rising costs and lagging demand to make their leading product out of a cheaper metal, Hoosier Love, Inc. found that a special treatment process was needed to clean and coat their Indy 500 memento, a tiny fake-jewel-studded replica of an Offenhauser engine on a jeweler's chain, to protect it from the corrosive effect of chlorine.

This process appeared in the ISO 9000 Manufacturer's Manual under the title, "The Dechloration of Indy Pendants."
