OSPHO–Rust Converter/Metal Primer
This item is no longer available.
Stabilize rusty surfaces prior to painting over with the system of your choice.
A metal treatment that, when applied to rusted surfaces, causes iron oxide (rust) to chemically change to iron phosphate—an inert, hard substance that appears black. Once dry, the treated surface can be overcoated with whatever paint system is desired. (Best results have been achieved with oil-base primers and topcoats. Test a trial sample before overcoating with epoxy or latex-based paint.) Application does not require the removal of light rust, however loose paint, rust scale, dirt, oil, grease and other accumulations should be removed first with a wire brush.
