Gathering Your Supplies

For minor surface rust, you can often tackle the repair yourself. You’ll need sandpaper (various grits), rust converter, primer, automotive paint, clear coat, masking tape, and safety equipment like gloves and eye protection.

Step-by-Step Rust Removal and Repair

Clean the Area: Thoroughly clean the rusted area with soap and water, removing any dirt and debris.
Sand the Rust: Use coarse sandpaper to remove the rust down to bare metal. Feather the edges to create a smooth transition.
Apply Rust Converter: Apply a rust converter to the affected area, following the manufacturer’s instructions. This will chemically convert the remaining rust into a stable compound.
Prime the Area: Apply several thin coats of automotive primer to the bare metal and surrounding area. Allow each coat to dry before applying the next.
Paint and Clear Coat: Once the primer is dry, apply thin coats of automotive paint that matches your car’s color. Finish with a clear coat for protection and shine.
