Car Rust Repair Explained – From Surface Rust to Deep Corrosion

Rust is more than just a cosmetic issue – it’s a sign that your vehicle’s metal is breaking down. Left untreated, rust can spread quickly and compromise your car’s safety, appearance, and value. At AutoStar Panel & Paint in Christchurch, we provide professional car rust repair services to restore your vehicle and stop corrosion in its tracks.

Why Rust Removal Matters for Every Car


New Zealand’s climate, with its salty coastal air and wet conditions, makes vehicles more prone to rust. Even small patches of surface rust can grow into serious damage if ignored. Acting early saves you money and extends the lifespan of your car.


The Difference Between Surface Rust and Deep Corrosion

Not all rust is the same. Knowing the difference helps you understand what repair your car needs:

  • Surface rust – This appears as small brown spots, usually caused by scratches or paint damage. It’s relatively easy to fix if caught early.
  • Scale rust – This occurs when surface rust is left untreated, eating deeper into the metal. Repairs may involve sanding and repainting.
  • Deep corrosion – When rust penetrates through the metal, it weakens structural parts of the vehicle. Professional welding and replacement may be required.

Our specialists will assess the damage and recommend the right solution, whether it’s treating minor surface rust or restoring strength to corroded panels.



Can Car Rust Be Repaired Permanently?

Yes – when treated correctly, rust damage can be repaired for the long term. At AutoStar, we:
