You can fix rust on your car by removing corrosion, repairing damaged areas and sealing the metal with primer and paint to prevent it returning. Even small rust spots can spread quickly if untreated, damaging both your car’s appearance and structural integrity.
With the right approach, you can stop rust early and restore your vehicle’s condition.
Rust forms in different ways, and the type you’re dealing with affects how you fix it.
● Surface rust
This is the earliest and most common stage of rust. It usually appears when your car’s paint is scratched or chipped, exposing the metal underneath. It’s the easiest type to fix if caught early and is usually suitable for DIY repair.
● Scale rust
If surface rust is ignored, it can develop into scale rust. This type starts to corrode the metal beneath, creating rough, flaky patches. You can still repair this at home, but it takes more time and more thorough preparation.
● Penetrating rust
This is the most advanced and damaging form. Penetrating rust eats through the metal, creating holes in body panels or even the car’s frame. At this stage, professional repairs or panel replacements are usually needed.
Before you get started, make sure you’ve got the right gear :
● Sandpaper or a wire brush to remove rust and loose paint
● Rust converter or neutraliser to stop corrosion spreading
● Body filler for deeper pits or holes
● Primer and touch-up paint to restore and protect the repaired area
● Microfibre cloths and clean rags for wiping down surfaces
● Protective gloves and eyewear for safety
Having the right tools helps the repair last and prevents rust from returning.
Fixing rust means removing corrosion, repairing any damage and sealing the metal with fresh paint. Fixing rust might seem daunting, but with the right approach it’s completely manageable. Follow these steps:
1. Clean the area thoroughly
Wash the rusted section with soap and water to remove dirt, grease and loose rust. Dry the area completely. Cleaning helps products stick properly and shows the extent of the damage.
2. Remove the rust
Use sandpaper or a wire brush to scrub away as much rust as possible. For stubborn areas, apply a rust converter to neutralise corrosion. Choose your tool based on how severe the rust is.
3. Fill any holes or pits
If rust has left behind deeper damage, apply automotive body filler. Let it dry fully, then sand it until smooth and level with the surrounding surface. Only fill areas that are safe to repair at home.
4. Prime and paint
Spray a rust-resistant primer over the repair and let it dry. Apply matching touch-up paint in thin, even layers. Once dry, finish with a clear coat to seal and protect the paintwork. Thin coats help prevent runs and uneven texture.
5. Let it cure
Allow each layer to dry completely before exposing your car to weather or washing it. Curing usually takes a few hours depending on the products used.
● Ignoring minor rust spots, which can spread quickly
● Using the wrong tools or cleaners that damage paintwork
● Failing to seal the repair properly with primer, paint and clear coat
● Using products that aren’t rust-resistant
Avoiding these mistakes helps the repair last longer and prevents repeat damage.
Prevention is easier and cheaper than repair. Here’s how to protect your car long term.
● Wash your car regularly to remove dirt, grime and road salt
● Apply wax or sealant to add a protective barrier
● Inspect and touch up paintwork promptly
● Keep the undercarriage clean, especially after driving on salted roads
