Rust is more than just an unsightly blemish on your car’s exterior. Left unchecked, it can devour your vehicle from the inside out, leading to expensive repairs and even safety issues. Whether you’re a first-time car owner or a seasoned petrolhead, recognising the early signs of rust and knowing when to act is critical for keeping your pride and joy on the road.
This guide will walk you through the most common indicators that your car needs rust proofing and why acting quickly can save you from future headaches.
Why is Rust Proofing Important?
Rust forms when metal reacts with moisture and oxygen in the air. Vehicles are particularly prone to rust due to their constant exposure to water, road salt, and varying weather conditions. What starts as a tiny spot of corrosion can quickly spread and weaken crucial structural components of your car, including the frame, engine bay, and undercarriage.
Rust proofing creates a protective barrier that stops moisture from penetrating and causing damage. But how can you tell when your car is crying out for some rust-proofing TLC?
Signs Your Car Needs Rust Proofing
One of the most obvious signs your car needs rust proofing is the presence of visible rust spots. These often appear as orange, brown, or red marks on your car’s bodywork, especially around the wheel arches, door edges, and boot.
At this stage, the rust might look superficial, but don’t be fooled. Surface rust can spread quickly and lead to more extensive issues if left untreated.
Pro Tip
Regularly inspect your car for rust, particularly in areas that are harder to see, like underneath the vehicle or near the exhaust. A flashlight can help you spot hidden trouble spots.
If you notice bubbles forming under your car’s paintwork, it’s likely that rust has started to develop beneath the surface. This happens when moisture gets trapped under the paint, often as a result of chips or scratches exposing the bare metal.
Bubbling is a red flag that shouldn’t be ignored. Once the rust breaks through the paint, the affected area can deteriorate rapidly.
Solution
Book a rust-proofing service as soon as you notice bubbling paint. The earlier you act, the easier it is to fix.
The underside of your car is constantly assaulted by road debris, water, salt, and mud, making it one of the most vulnerable areas for rust. If you hear strange creaking, groaning, or rattling sounds from below, it might not just be wear and tear. Rust could be eating away at your car’s frame or joints.
Maintenance Tip
Invest in regular undercarriage inspections, especially if you live in a coastal area or somewhere that uses road salt during winter.
Inspect the nuts, bolts, and screws connecting your car’s components. Rust creeping around these small details is a tell-tale sign that moisture has infiltrated your vehicle’s structure. While it might seem minor, rusty bolts can break or become impossible to undo, complicating basic repairs or maintenance.
Rusty screws or bolts are also a sign that other, less visible areas of your car could be corroding.
Your car’s undercarriage is its first line of defence against the elements, but it’s also exposed to more hazards than any other part of the vehicle. Constant exposure to water, sand, and salt can create corroded patches along the floor pan, fuel lines, or suspension components.
When inspecting the undercarriage, be on the lookout for colour changes (such as dull orange streaks) or flaking metal. These signs are indicators that rust-proofing is overdue.
If your car’s interior feels damp or if you spot water pooling in areas like the footwells or boot, take action immediately. Moisture build-up inside the vehicle is not only unpleasant but also accelerates rust formation in hidden areas like door panels and the floorboards.
Check These Areas for Dampness
Addressing leaks and rust-proofing your car can prevent moisture from wreaking havoc on your vehicle.
Paint is your car’s first defence against the forces of nature. If the paint is peeling or has been chipped due to small impacts or scratches, it exposes the underlying metal to moisture and air, creating the perfect environment for rust.
Left untreated, these small imperfections can become rust hot spots.
Quick Fix
Cover chips with touch-up paint as a temporary solution. Then, schedule a rust-proofing session to prevent further damage.
Even if you haven’t noticed visible signs of rust yet, your location plays a huge role in how vulnerable your car is. If you live near the coast, road salt or humid sea air can quickly corrode exposed metal. Likewise, if your area experiences heavy snowfall, the salt and grit used to clear icy roads can accelerate rust formation.
Prevention really is better than cure when it comes to rust. If you’re in a rust-prone area, consider scheduling routine rust-proofing services to protect your car year-round.
Why Rust Proofing is Worth the Investment
Getting your car rust-proofed isn’t just about aesthetics; it’s about long-term performance, safety, and value.
Here’s why it’s worth it:
Keep Rust at Bay
Rust might be an unwelcome visitor, but with routine maintenance and the right preventative measures, you can keep it under control. Inspect your car regularly for the warning signs mentioned above and act quickly to ensure small problems don’t become big ones. Take special care of high-risk areas like the undercarriage, wheel arches, and paintwork.
