Identifying and Assessing the Rust

Before you start, you need to assess the damage. Is it truly surface rust or something more severe? Surface rust appears as small, discolored spots or patches on the car’s paint. It hasn’t yet penetrated the metal underneath. If the rust is bubbling, flaking, or has created a hole, you might need professional help.

Tools and Materials You’ll Need

• Sandpaper (various grits, starting with 180-grit)
• Masking tape and paper
• Primer
• Touch-up paint
• Clear coat
• Rubbing compound
• Microfiber cloths
• Safety glasses and gloves
• Rust converter (optional)

Step-by-Step Guide to Fixing Surface Rust

1. Clean the Affected Area: Thoroughly wash the rusted area with soap and water and dry completely. This removes dirt and grime that can interfere with the repair process.

2. Mask the Surrounding Area: Use masking tape and paper to protect the surrounding paint from scratches during sanding.

3. Sand the Rust: Start with a coarser grit sandpaper (like 180-grit) and gently sand the rusted area until the rust is removed and the bare metal is exposed. Gradually move to finer grits (220, then 320) to smooth the surface. If you also have scratches, check out our guide on how to fix paint scratches on your car.

Removing Surface Rust with Sandpaper

4. Apply Rust Converter (Optional): A rust converter chemically transforms the remaining rust into a stable compound. Follow the manufacturer’s instructions.

5. Prime the Area: Apply a thin, even coat of automotive primer to the sanded area. This protects the bare metal and provides a better surface for the paint to adhere to. Allow the primer to dry completely. Do you have cracked paint? Learn how to fix cracked car paint.

6. Apply Touch-Up Paint: Apply thin coats of touch-up paint that matches your car’s color. Allow each coat to dry before applying the next. Multiple thin coats are better than one thick coat.

7. Apply Clear Coat: Once the touch-up paint is dry, apply a clear coat to protect the paint and give it a glossy finish.

8. Polish and Buff: After the clear coat has dried, use a rubbing compound and a microfiber cloth to blend the repaired area with the surrounding paint. This will create a smooth and seamless finish. If you have small dents, find out how to fix small dents in cars.
