Abstract
A novel, metal protective solution is described. This solution of two parts, the first part being a mixture of one aqueous potassium silicate and two aqueous sodium silicate solutions and the second part comprising approximately equal amounts of acetic acid, zinc oxide, copper sulfate, clay and sodium bicarbonate, is stable, relatively inert and has a long shelf-life. It may be applied to metal surfaces to prevent corrosion and rust from forming thereon.
