Description
– 1 qt.
– When applied to rusted surfaces, it resists/retards rust in chemical change on drying to a tough, hard surface ready for priming.
– A paint job will last longer after an application of OSPHO because subsequent paint coating securely attaches itself so that moisture and oxygen normally do not attack the metal.
– OSPHO is water-thin, can cover a larger area than paint, and goes on easily.
– It is equally effective for exterior and interior work alike.
