CRC Rost Flash, 500ml is double strong against rust. A cooling agent freezes the sprayed surface to up to –40 °C. The rust and dist structure is demolished, giving rise to the smallest cracks and intermediate spaces. This crack-effect lets the capillary-active agent penetrate quickly and deeply. The penetrating oil reduces the frictional forces so that the fixed screws, bolts, nuts, washers can be loosened quickly without any effort. CRC Rost Flash, 500ml is free of acids and silicone, leaves behind a fine protective film and in this way prevents further formation of rust.
