A special refrigerant propellant freezes metal to as low as -50°F/-45°C causing contraction of the metal and creating micro-cracks in the corrosion and galvanically fused metal parts to free them
A penetrating release agent breaks down and flushes out the rust after the metal contracts and breaks loose
For best results spray the seized part for 10 - 20 seconds or more depending on severity then let sit for several minutes
