This official action bears out the experi ence of the leading American manufactur ing concerns who have been protecting their products from rust by the Parker Process for several years. A Book on Rust Proofing for Industrial Executives No matter what you manufacture-if you use steel or iron you will find it interesting to read the recently published Parker Process Book. This ex plains how the Parker Process is rapidly reducing the great toll rust takes annually from our steel supply-how it is now being used on metal articles from automobiles to fountain pens-from building hardware to typewriters-and how easily you can apply it to your own product in your own plant without interfering in any way with your present manufacturing plans.
