Corrosion Block 32oz Pump Bottle - Case of 4

The Corrosion Block 32oz Pump Bottle - Case of 4 is designed for marine and industrial equipment that needs dependable protection against moisture, rust, and corrosion. The penetrating liquid uses polar-bonding chemistry to move into joints, connectors, fasteners, and corrosion cells, displace moisture, and leave a clear hydrophobic protective film.

Because the film remains after displaced moisture evaporates, it can protect electrical and mechanical components without leaving the heavy waxy coating associated with some corrosion products. Common marine uses include battery terminals, connectors, switches, lighting circuits, engines, alternator leads, and electronics.

The larger liquid format is useful for refill, shop, fleet, or broad-area maintenance where repeated corrosion treatment is required. Surfaces should be accessible and reasonably clean so the product can reach the metal or component being protected.

• The formulation is built to protect metal in wet, humid, and salt-exposed environments.
• The fluid reaches small spaces and leaves a moisture-resistant film after application.
• The product can be used across a broad range of compatible boat and equipment components.
• The package format suits repeated maintenance and professional use.
