Superon Bright Zinc Spray is a quick drying, light-duty, sacrificial coating that protects ferrous metals from oxidizing. It creates a barrier film between the environment and the base metal to prevent the formation or spread of rust and corrosion. It also provides the appearance of a high shine, hotdip galvanized, bright metallic finish. Superon Bright Zinc Spray is excellent for touch-ups to scratches, dents, welds, wear or machined edges on aluminum and other high shine metal substrates.
