Ospho can be used on all ferrous and non-ferrous metals and is a great protectant of new metals. Iron oxide is always present in new metals as it hides deep inside the metal pores. With a simple application, Ospho attacks and converts whatever iron oxide it comes into contact with changing it to Iron Phosphate, as well as leaving a layer of zinc phosphate to seal and protect the metal from flash rusting.
- Converts iron oxide to iron phosphate
- Grows zinc phosphate to seal and protect for the future
- Can be used on all ferrous and non-ferrous metals
