Rust is the ugly reddish-brown compound gnawing at the metal of your auto. This structural parasite spreads quickly and eats away your most prized wheels. Once weakened, your automobile might even end up splitting in half—ouch!
Better do something about your car’s rust issues, or else you will jeopardise its safety, strength, beauty and lifespan.
Our recommendation? Stop the damage and keep your car in tip-top shape with a proper rust repair on vehicle.
Understanding Rust
Rust can happen due to moisture, salt and any damage inflicted to the body of the car. It occurs when iron reacts with oxygen and water, creating a chemical reaction called oxidation.
Oxidation corrodes the metal, producing noticeable rusts that can heavily damage the surface of the car.
Common Areas Affected by Rust
Rust is an ever-present matter for many vehicles. That’s why it’s important that you know where rust commonly pervades in the car so you can easily check for rust formations and prevent it.
That said, which areas in your Audi do rust frequently wreck?
Wheel Wells
Wheel wells are prone to rust because they frequently encounter moisture and salt. The swift build-up of small amounts of liquid can lead to rust formation very quickly.
Undercarriage
Another spot in your car commonly impacted by rust is the lower portion of your vehicle. Since it’s beneath the body, it is constantly exposed to elements like debris, salt and water, which are major factors in rust creation.
Doors
Your car’s door is also susceptible to rust because it’s laid bare to the elements. Especially the seams and edges of the frame, these sections can easily trap water. Over time, the trapped moisture can prompt the development of rust.
Hood and Roof
Worn parts or scratches on the roof or the hood of your car can result in oxide build-up. Chipped areas can allow the water to seep through the metal surface and rust.
Signs of Rust Damage
Before rust ever becomes a major eyesore, there are actually warning signals waving the “I’m rusting inside” flag. If you can detect them, it’ll be easier for you to stay ahead of the game.
Flaking Paint
When rust develops, the surface of your vehicle will start to blister. So, if you see flakes falling away on your car’s body, it’s a sign that rust is creeping into the metal.
Rust Spots
Do you see any odd stains or spots on your auto’s body? If you do, watch out, because that’s an indicator that rust is slowly infiltrating the metal.
Holes in the Vehicle’s Body
When small holes start to develop in your car’s frame, rust is working its way to weaken your automobile’s surface.
The Smell
So, how does a rusting car smell? Well, not so nice. If you start sniffing a funky odour flying around from your auto, that’s rust trying to break your machine's body.
Early detection is really important to prevent further damage to your favourite asset. If you can see them earlier on, you can leverage timely repairs and prevent extensive damage from developing, costing you expensive and time-consuming fixes.
Tools and Materials Needed for Rust Repair
Rust is your car’s problem that needs to be dealt with now and not later. To conquer your rust issues, first thing first, gather the right tools and materials.
Here’s what you need to remove rust:
• Sandpaper (120 to 140 grits)
• Rag
• Paintbrush
• Steel brush
• Rags
• Primer
• Body filler
Rust converters, known to be rust killers, can be leveraged for rust repair. These chemical solutions convert iron oxides, aka rust, into a more stable compound that can stop corrosion.
Apart from that, you can also use protective coatings that are highly resistant to moisture, creating a barrier that protects the surface from corrosion and deters new rust formation.
On top of these remedies, epoxy-based products and rust inhibitors can be applied as well to ease off the rusting process and strengthen the surface. As such, you can protect your car from future wear and tear and ensure a lasting repair job.
Step-by-Step Rust Repair Techniques
Preparation
First thing: clean and remove any dirt or rust. This way, it’s easier for the repair treatments to adhere to the surface.
Removing Rust
The point is to eradicate as much rust as you can.
That said, to effectively remove the rust from your car’s metal, you can use a wire brush or sandpaper (80-120 grit). And in a back-and-forth motion, start scrubbing the affected area.
If the rust is more stubborn, you can use a wire brush connected to a drill to do heavy-duty de-rusting.
When you free the metal surface of rust, you can stop sanding and proceed to clean the area with a soft cloth to remove any leftover debris and secure a smooth foundation before repair.
Once you’re done with the manual work, apply chemical rust removers and converters. The purpose of this chemical solution is to transform the rust into a non-reactive layer, preventing it from causing damage.
In a few minutes, that ugly red-orange substance will slowly change and be nothing but an inert black matter.
Filling and Smoothing
Body fillers are a putty-like substance used to repair the damages to your vehicle's body and return it to its original form.
To fill the dents and small holes, use a putty knife and apply body fillers, making sure it’s equally filled. After the filler has dried, start sanding the area in a circular motion, ensuring it’s even and has no gap with the surrounding metal.
You can make adjustments afterwards to ensure the surface is smooth and free from any imperfections.
Painting and Protection
Prime the area after using chemical rust removers to prevent the rapid formation of rust.
After priming, apply a durable paint designed for metal surfaces, allowing proper drying time before applying the next coat.
These protective coatings are important to prevent future rust, serving as a defence mechanism for your metal. They provide a waterproof layer that mitigates the risk of oxidation, preventing accumulation of corrosive materials and prolonging the lifespan of your vehicle.
Preventive Measures
Prevent the rust from taking root on your car! How are you going to do that?
Well, check out these tips and ensure your sleek ride stays sharp and rust-free.
Regular Maintenance
Environmental contaminants like mud and debris will find their way to stick to your car’s exteriour, especially if you’re driving in intense conditions. With the weather and the chemicals on these substances, it’s easy for the oxidation process to kickstart and form rust.
However, by routine inspections and regular washing, you can spot these corrosive elements and completely remove them, unsettling the conditions that prompt rust development.
Protective Treatments
Aside from the basic preventive measures, you can also further your car’s protection with the following treatments:
Waxing
The wax on your car will create a barrier guarding your paint from moisture, UV rays and other environmental attacks.
As you know, this protective layer is critical because rust thrives in moist places. Your chipped and faded paint reveals the metal underneath, inviting the rust to take root. But with waxing, you can prohibit rust formation.
Undercoating
Undercoating is another treatment that creates a robust shield underneath your car. It’s a defensive layer for the bare metal, totally exposed to many contaminants down there.
This process ensures your car remains rust-free and promotes its structural integrity, preserving its functionality and showstopping beauty.
Sealants
Sealants protect your car’s paint and exterior against moisture, debris and UV rays. They serve as a barrier blocking the natural elements from penetrating the metal surface and consequently, inhibiting rust growth.
DIY vs. Professional Repair
Sure, you can choose to DIY your rust repair. It’s a more practical choice, especially if you’re dealing with manageable rust. You get to control your time and handle the repair most cost-effectively.
However, DIYing takes time and patience. Without the right tools and knowledge, you can easily compromise the repair process and incur more damage.
Meanwhile, professionals have the knowledge, skills and resources to ensure proper repair on your car’s surface. They can handle complex rust damage in large spaces and ensure the work done is superb and long-lasting.
Thus, if you’re facing extensive rust issues that compromise the integrity of your car, we advise you to ask for professional help.
