Ospho is nothing more the Phosphoric acid that can be found in many
products. One being METAL-READY by POR-15 http://www.stoprust.net You can
find Phosphoric acid at pretty much any paint store in generic form and
cheaper
The Ospho and METAL-READY. Ospho doesn't *seal* anything. It converts the
Rust chemically to a zinc finish so paints can adhere to the surface better.
If left untreated very long any surface treated with Ospho will start
rusting again. If you looking for a simple and quick way to paint a rusted
surface check out the POR-15 Paints. They also recommend treating the
surface first with Phosphoric acid to prep the surface for better bonding.
