Updated chairs (three found on a curb, the homeowner said yes, the intent was for someone to take them). The upholstery was faded and worn and the finish chipping and rusted. A good brushing (care of a wire brush attachment for my electric drill), two coats of rustoleum's rust reformer, followed by several passes of apple green rustoleum. Finished off by recovering the seats with outdoor fabric in a yellow and black paisley.
Stop rust in its tracks with Rust-Oleum® Stops Rust® Rust Reformer. A layer of this flat-black coating bonds with rusty metal and instantly transforms it into a non-rusting surface. No need to sand down to bare metal, simply spray directly onto rust.
