How to Fix Rust on a Car

If your car’s paintwork starts bubbling or peeling, it could be a sign that rust has set in. Rust can cause serious issues for your vehicle if left untreated, eroding the metal on the chassis and frame. However, rust repair is relatively straightforward and is a worthwhile investment to prolong your car’s lifespan if it’s in the early stages of rusting. Our guide covers what causes rust, ways to prevent it, how to treat rust on a car and the best products to use.

What causes cars to rust?

Any part of your vehicle’s exterior can rust, from painted areas on the car’s body to the undercarriage. The undercarriage is one of the most susceptible areas to rust since it’s exposed to significant moisture and debris from the road. Other common areas where rust may occur include the exhaust, brake pads, suspension, wheel wells and doors.

Consider checking your car for rust regularly so you can treat the problem as soon as possible and prevent corrosion from worsening, which could lead to costly repairs.
