Key Advantages

Superior Creep: High capillary action allows it to penetrate microscopic crevices in rusted or jammed threads quickly.

Corrosion Protection: Leaves behind anti-corrosive additives to provide long-term protection against rust.


How to Use

Shake the can well before use.

Spray directly onto the seized part or rusted bolt.

Allow the product to penetrate and work for a few moments.

For stubborn or heavily oxidized connections, repeat the application and allow the agent to soak longer.
