It penetrates flaky rust, chemically converts oxidation to a dark, inert layer, and leaves metal ready for surface finishing without extensive mechanical removal. The product is widely used on cars, trucks, boats, RVs, motorcycles and ATVs and is compatible with many paints, decals, wiring and hoses when applied per instructions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Ospho stop rust and prepare metal for painting?\u003c\/h3\u003e\n\u003cp\u003eOspho’s active chemistry reacts with iron oxide to form a stable, non-porous layer that seals the metal.
