Every few weeks someone brings a car in here in Goodwood, points at a bubble under the paint on a sill or a wheel arch, and asks the same question: "My insurance will cover this, right?"
The honest answer, almost every time, is no. And once you understand what rust actually is, it makes sense why — and why we, like every reputable panel shop, won't put a lifetime guarantee on a rust repair either.
Rust Is Wear and Tear, Not an Accident
Motor insurance in South Africa is built to cover sudden, unforeseen events — a collision, hail, theft, a break-in, a tree falling on your bonnet. Rust doesn't happen suddenly. It's a slow electrochemical process: bare metal, moisture, and oxygen reacting over weeks, months, and years.
Every standard motor policy in the country carries a wear-and-tear and gradual-deterioration exclusion. Rust falls squarely into that category, alongside things like worn brake pads, faded paint, and a tired clutch. Insurers aren't being difficult here — corrosion is specifically the kind of maintenance issue that premiums were never priced to cover.
The only time rust repair enters an insurance claim is when it's a direct, incidental result of accident damage that's being repaired anyway — for example, if a panel was dented in a collision and surface rust started forming on the exposed metal edge before you got it in for repair. Even then, the insurer is covering the collision damage, not the rust itself.
Why We Won't Guarantee a Rust Repair for Life
This surprises people, so it's worth explaining properly.
When we repair a rusted panel — cutting out the affected metal, welding in new steel, treating and repainting it — we're giving you a repair that's as good as the panel can be made. What we can't control is everything that happens to that car afterwards:
- Where you park it. Cape Town's salt air near the coast accelerates corrosion dramatically compared to the southern suburbs.
- How it's washed (or not washed). Salt, brake dust, and road grime left to sit are exactly what restarts the corrosion cycle.
- Stone chips and scratches that expose bare metal again and are never touched up.
- The condition of the rest of the vehicle. If a car is rusting in one place, it's very often an early sign of the same thing happening elsewhere out of sight — inside sills, behind trim, under seals.
A "lifetime rust guarantee" would mean promising to control all of those things for as long as you own the car. No panel shop that actually understands metal will make that promise, because it isn't ours to make. Anyone who offers you an unconditional lifetime rust guarantee is either not going to be around to honour it, or has priced the risk into the quote in a way you're not seeing.
What we will stand behind is the quality of the workmanship on the day — proper metal cut-back to clean steel, correct weld penetration, and full anti-corrosion treatment and primer before paint, done to the standard the repair deserves.
What Actually Slows Rust Down
- Regular washing, especially the underside, if you're anywhere near the sea
- Prompt touch-ups on stone chips before they spread
- Checking drain holes in doors and sills aren't blocked
- Dealing with small rust spots while they're small, not once they've become a hole
