Underbody rust proofing plays an important role in maintaining your vehicle, especially when you drive frequently on salted roads or live in an area with harsh weather conditions.
It can significantly extend the life of your car by protecting it from the corrosive elements that cause rust.
At Autobedliners, we specialise in advanced coatings and rust-proofing solutions that stand strong in the toughest environments. In this blog post, we’ll cover everything you need to know before you rust-proof your vehicle’s underbody.
Let’s get started!
What is Underbody Rust Proofing | Why is It Essential?
Keeping your vehicle in great shape involves more than just washing and waxing the outside.
One crucial but often overlooked area is the underbody. This is where underbody rust proofing comes which offers vital rust defence.
“Underbody rust proofing is a specialised treatment applied to the underside of vehicles to shield it from rust and corrosion.”
It creates a protective barrier that defends against moisture, road salt, dirt, and other contaminants from the environment. By providing this barrier, underbody rust proofing helps prolong your vehicle’s lifespan and maintain its structural strength.
Why is underbody rust proofing so important?
Rust occurs when iron or its alloys react with oxygen and moisture. This process speeds up with factors like road salt, humidity, and severe weather conditions. Over time, rust can weaken your vehicle’s structure, leading to expensive repairs and safety risks. Thus, protecting the underbody with rust proofing is crucial for maintaining your vehicle’s overall health and durability.
When is the Best Time to Rust Proof Your Vehicle?
The best time to rust proof your vehicle is before winter arrives, ideally during the summer or spring months.
Rust proofing in spring or summer allows the coating to adhere well without the interference of road salt. Alternatively, applying rust proofing in fall shields your vehicle from winter’s harsh elements and corrosive road salt, which can speed up rust formation.
For new vehicles, rust proofing early helps prevent rust from starting and ensures lasting protection. If you own a used vehicle, it’s still worthwhile to rust proof it, especially if you spot any signs of rust. Top of FormBottom of Form
How to Prepare Your Vehicle for Rust Proofing?
Before going for rust proofing your vehicle, it’s important to make sure the underbody is clean and free of any existing rust or damage.
Here’s how to get your vehicle ready:
-
Cleaning the Underbody
Thoroughly clean the underbody to remove dirt, grime, and any old rust. This step is important to ensure the rust proofing coating sticks properly.
If there are signs of rust, use a wire brush or rust remover to get rid of it before applying the protective coating.
Pro Tip: Pay special attention to cleaning the undercarriage and wheel wells where snow, dirt, and mud can accumulate from tyre splashes. Properly preparing these areas ensures the rust proofing treatment can provide maximum protection for your vehicle.
-
Inspecting for Damage
Examine the underbody closely, especially in hidden spots like seams and joints, for any rust formation. Fix any structural issues or deep rust spots to ensure a smooth and effective rust proofing process.
Choosing the Right Rust Proofing Method
Wondering what is the best car rust protection for a car? Rust proofing treatments come in various forms, each with its own pros and cons.
Let’s explore the different options to help you find the best fit for your time and budget.
-
Conventional Spray Rust Proofing
This method has a long-standing history, offering flexibility in application. You can opt for an undercarriage treatment or a comprehensive spray covering engine bays, underbody, and topsides. It provides sound deadening and abrasion resistance, ideal for comprehensive vehicle protection.
-
Grease-Based Treatment
For maximum rust protection, consider a grease-based treatment. It’s a bit pricey but lasts the lifetime of your car with occasional touch-ups. Dealerships or specialized shops typically handle this.
-
Oil-Based Treatment
The most common, practical and effective choice is an oil-based treatment. It’s affordable but needs yearly reapplication to stay effective, especially if your car is prone to rust. Apply before winter for best results.
-
Chemical Rust Proofing
Using chemicals like phosphate conversion or anti-rust wax, this method involves galvanizing the surface to enhance protection. It offers diverse options and is effective in preventing corrosion over the long term.
-
Cathodic Rust Proofing
This method controls corrosion by making the metal the cathode in an electrochemical cell. It involves connecting a sacrificial metal anode to the primary metal, which corrodes first, thereby protecting the primary metal from rust.
-
Electronic Rust Protection
Considered advanced, this method involves capacitive coupling with your vehicle’s battery system. It creates a negative charge that inhibits rust and oxidation by forming an excess field of ions on metal surfaces. It combines the benefits of other methods but with extended longevity and cost-effectiveness.
Benefits of Underbody Rust Proofing
- It Extends Your Vehicle’s Lifespan: Rust proofing protects critical components of your car’s underbody, such as the frame, exhaust system, and suspension parts, extending the overall lifespan of your vehicle.
- Improves Safety: A rust-free underbody ensures that essential parts remain intact and functional, enhancing the safety of your car.
- Increases Resale Value: A well-maintained, rust-free vehicle has a higher resale value, making rust proofing a wise investment.
- Save You Money: Preventative rust proofing can save you money on future repairs and replacements due to rust damage.
FAQs
How long does underbody rust proofing last?
The longevity of rust proofing depends on the type of coating used and environmental factors. Oil-based coatings typically last 1-2 years, while tar-based coatings can last manys years with proper maintenance.
Can I rust proof my vehicle myself?
Yes, but professional rust proofing is recommended for the best results. DIY rust proofing can be less effective if not done correctly.
Is rust proofing worth the cost?
Yes, rust proofing can save you money on future repairs and increase the resale value of your vehicle, making it a worthwhile investment.
Will rust proofing void my vehicle’s warranty?
No, rust proofing generally does not void the vehicle’s warranty. However, it’s best to check with your manufacturer or dealer for specific details.
How often should I rust proof my vehicle?
It’s recommended to reapply rust proofing every 1-2 years, depending on the type of coating and environmental conditions.
