Step 8 · Apply Protective Finish

Once the item is clean and completely dry, apply a suitable protective finish. For ferrous metals, a primer followed by paint is common. Other options include clear coats, waxes, oils (like WD-40 or mineral oil for tools), or specialized metal protectants. Ensure the finish is applied evenly and according to the product's instructions. This step is crucial to maintain the rust-free condition of the item.
