- ClumsyPilot 5y agoThis is how weathering steel works, but for all other cases the instructions are to remove the oxidized layer and apply a protective coat of paint, because rust is typically pourous and provides no protection, but traps moisture. Also stainless steel has an oxidised protective layer, but its transparent so we don't call it rust
