Abstract
Metal surfaces, after being cleaned of rust with an aqueous acid solution, are rinsed with an aqueous solution of a chelating agent and an ammonium or alkali metal silicate. Such rinsed surfaces remain rust free for extended periods of time. When coated with primer and top-coat paints, excellent durability and corrosion resistance are obtained.
