This acceptpnceisbased, o a great extent, on its marked ability to land up against moisture, a powerful actor in the rusting process. Now, scientific research into the inicrcnt properties of the pigment itself, hows just how and why Red Lead rcists the effects of water. Briefly, there re four reasons: ..

Water permeability tests of paint fiimB (see illustration at lower left) show, beyond question, that Red Lead is one of the most effective metal protective pigments, because of its stubborn resis tance to the passage of moisture through RED LEAD Improves All Metsl Protective Paints The rust-resistant properties ofRed Lead are so pronounced that it improves any metal protective paint. So, no matter what' price paint you want, you'll get a better paint if it contains Red Lead. the film. 1 3.

On the other hand, the solubility losses of Red Lead paint films are practically negligible. 4.
