The Finish Line Chill Zone Aerosol is engineered to free up seized parts. This spray is designed to get rid of rust, cold welding or loosen any stuck components. This formulation combines a penetrating oil, with a chemical that gives an exothermic reaction, cooling the part rapidly to -40 degrees Celsius, causing the metal to contract rapidly. This chilling process creates micro cracks in the corrosion, allowing a release agent to penetrate and loosen up the rusted seized part leading to rust to flake off, and for seized parts to become un-seized. Before giving up on seized crank bolts and pedals, or rusted chains and derailleurs, or frozen-in-place seat posts give Chill Zone a shot!
