Waxoyl Professional 120.4 is a high-performance product that provides long-lasting protection against corrosion. The product is based on molecular wax with powerful organic corrosion inhibitors, in which the molecules are electrically charged, which allows the product to adhere to the metal walls and to stop the corrosion process.
