"" ', How RED LEAD stops Eleefro-cliemie&E Action ...basic casus I Rusting Modern science reveals many reasons why Red Lead has earned its place as the "standard" metal protective paint. metal. It effectively inhibits electro chemical action, and; the consequent cor rosion of the metal monly used in metal protective paints, including many o the fast-drying resin types. One very basic factor is Red Lead's Natiirally, for continued protection, RED LEAD improves ALL Metal Protective Paints ability to halt electro-chemical activifythe fundamental cause of rusting. In this electro-chemical action, weak currents are generated, because of chem the film must remain unbroken.: Sere again, in the same way, Red Lead: heals ^nv smjall breaks in the protective shield ' due to abrasive action or other causes. The rUst-resistant properties of Red Lead are so pronounced that it improves any metal protective paint So, no matter wftat price paint you want, you'll get a ical and physical differences in the metal, ThuS&the metal remains in a, rust- better paint if it contains Red Lead. as well as local differences in environ inhibited condition as long as Red1 L^ad ment.

These electro-chemical conditions are always present; but Red Lead eliminates their harmful effects- '^ Here's how: Red Lead possesses unique properties which enable it rapidly to convert the iron solubles into stable com pounds.
