Rust-Oleum has a product aptly named Rust-Reformer. All Rust-Oleum claims you have to do with Rust-Reformer is paint it over a rusted metal surface and the Rust-Reformer binds the rust together with the substrate to form a surface that can be painted. Paint over corrosion? -- Hmmm, doesn't sound like it would work does it. Well, Rust-Oleum did it and boy does it work. Rust-Oleum Rust-Reformer can be used on any metal surface including rusted metal roofs, shed and fences, rusted car parts, rusted railings and rusted metal furniture. Rust-Reformer stops the progress of rust and does not leave behind an environment where more rust can develop. Of course as with any product Rust-Reformer has its limitations. If a surface is rusted completely through Rust-Reformer cannot fill in the area and create a new surface -- it is a hole. Rust-Reformer is primarily used on rusted spots that have still retained their strength even with corrosion and have enough metal left to bind the rust to.
Using Rust-Oleum Rust-Reformer is actually a very easy job. It comes in a spray can for easy application. Use a coarse grit sandpaper to remove loose and flaking areas of corrosion either by hand or with a pwoer sander. Don't take the rusty areas down to the bare metal, that isn't necessary, just use the sandpaper to pull off loose rusted sections and pieces. Sweep up or vacuum the loose rusty particles. Spray an even coat of Rust-Reformer over the rusted metal wait 10 to 15 minutes or so, spray another coat over the first coat, wait another 10 to 15 minutes and spray a third coat. Allow the Rust-Reformer to dry until it is no longer tacky to the touch and paint over the formerly rusty surface with Rust-Oleum rust inhibiting paint. Choose a paint color to match an old paint color or choose a brand new paint color. You can choose to use another brand of metal paint because Rust-Reformer is compatible with most paints both solvent based and oil based. Although I wouldn't recommend a different brand in terms of quality and performance.
With this rust binding covering you no longer have to wire brush corrosion off or sand or grind rust off of a metal surface. A light sanding to get large flaky area off teh surface is all it takes. Rust-Oleum Rust-Reformer can be used on indoor surfaces or outdoor surfaces.
Rust-Reformer is not a long term solution and reapplication may be necessary to keep your metals from corroding in the future. It does extend and preserve the life of metals. There are many other coatings available to bind rust or inhibit rust, but in terms of application and lasting value Rust-Oleum comes out on top.
