The ROST FLASH 500ML is a quick acting Penetrating Oil Lubricant with freeze effect. A no compromise product that destroys the structure of rust and corrosion by thermal shock. The created fissures allow a fast penetrating of the oil through the oxides and soil to free corroded fasteners and mechanical components. Aerosols are equipped with the 360° (upside-down) spray valve and extension tube for added convenience. Eases quick disassembly of mechanical components, fittings, assemblies, nuts and bolts and other close tolerance fasteners. It is safe for all metals and for most plastics and rubbers (if in doubt, on-the-job testing prior to use is advised).
