4wd Underbody Rust Protection: Everything You Need To know

4wd Underbody Rust Protection vs Electronic

So, you’re looking for underbody rust protection for your 4WD.

If you’re looking for rust protection, you’re pretty much wanting one thing – No rust in your vehicle.

But you may not be aware of your options, pricing and what you will get.

Basically, you’ll have 2 options for rust proofing your vehicle:

1. Underbody rust proofing Sprays – which stop rusting from taking place in the first place.

2. Electronic Systems – which stop or slow the reaction by replacing the electrons in the vehicle using a negative charge.

To make sure you get the best rust protection for your vehicle, we’ve broken down these options side-by-side to give you everything you need to make a confident buying decision.

4wd Underbody Sprays

How Do underbody 4×4 sprays work?

Sprays attempt to stop corrosion from forming by coating the vehicle or structure and preventing the iron & oxygen coming into contact.

By spraying the underside of your vehicle, you create a physical barrier of protection for your vehicle.

Positives

1. Stops rust from forming
2. Prevent structural and surface rust
3. You can check them anytime
4. Professionally applied

Negatives

1. Don’t cover the entire vehicle
2. Only work on the areas applied
3. May need re-application or touch ups
4. Require check-ups every 6-12 months
5. Complicate Machanic Work (Due to the vehicle being coated)
6. Won't stop existing rust

Price

Main Spray$500-800
Touch Ups$30-100
Re-Sprays$300-500
Total Cost Over 10 Years$500-1100
Cost Per Year (Averaged Over 10 Years)$50-110

Overall Verdict On Sprays

4WD Underbody Rust Protection

Whilst on-going maintenance fees and time commitments may discourage you from choosing an underbody spray, it doesn’t mean that they’re a bad option.

If maintained, a quality spray can see you through any harsh environment that would otherwise nurture rust on your vehicle. 

The initial set-up cost is affordable in comparison to many other solutions on the market, which is great if you haven’t yet got the finances to put towards a better level of protection.

Ratings Explained:

Level Of Protection: Sprays protect against both structural and surface rust, however, do not cover the entire vehicle and often leave many areas that can’t be reached without protection. 

Maintenance Time: Sprays require on-going in-house checkups from your installer 

Install Time:  Install done entirely by the installer, but will require a few hours

Total Cost: This will depend on the type of spray you get. 

Maintenance Cost: Depending on the amount of touch up work or reapplication required

Install Cost: This is included in the cost of the system 

Overall Rating: Taken from an average of the other variable

Electronic Rust Protection

How does electronic rust protection work?

Electronic systems aim to replace lost electrons in steel using a negative charge, ultimately reducing the rate of corrosion.

By fitting an ERPS, you stop rust from both:

  1. Forming
  2. Spreading
This is due to the rusting process slowing or stopping entirely.

 

Positives

1. They Protect The Entire Vehicle
2. Reduce Paintwork Oxidation - Meaning paint retains shine
3. Can Be Self-Installed
4. A One-Time Fit
5. No on-going maintenance time or cost
6. Last 10+ Years
7. Transferable to your next vehicle
8. Work on vehicles with or without rust

Negatives

1. You Can't See Them Working
2. Don't Protect Against Surface Rust
3. Vary Widely In Quality and Results depending on the brand

Price

Main System$500-800
Total Cost Over 10 Years$500-800
Cost Per Year (Averaged Over 10 Years)$50-80

Overall Verdict On Electronic Rust Prevention

Does Electronic Rust Prevention Work

The major benefit an ERPS system is the level of protection – offering full protection for your vehicle, top and bottom.

With minimal maintenance time and guaranteed performance an ERPS system could be the best fit if you’re looking for a ‘set-and-forget’ solution to rust.

The ERPS system can be self-installed to save on install cost or installed professionally. 

While this install cost may be more expensive, by installing through one of our registered installers, you will also get a 10-year corrosion warranty – guaranteeing no rust in your vehicle (conditions apply)

Ratings Explained:

Level Of Protection: ERPS systems protect the entire vehicle bottom and top – this includes areas that sprays can’t reach. 

Maintenance Time: Once fitted, there is no on-going maintenance required, other than checking the light on the system once a month. 

Install Time: This will depend on the type of system fitted and whether it’s installed by yourself or an installer or auto electrician. 

Total Cost: Depending on the type of system you get 

Maintenance Cost:  Due to having no sacrificial parts or wearing comonents. 

Install Cost:  Again, depending on the type of system fitted and whether it’s installed by yourself, a professional installer or auto electrician.

Can I Do Both?

Hopefully you have a better understanding of rust prevention and your options.

But you may be wondering – can I get both a spray coating and electronic system?

And Yes – you absolutely can.

A ‘combo’ approach is probably the best level of protection you can have – however, it may be necessary and will vary from person to person.

We recommend fitting an electronic system first – to ensure that you’re able to correctly install it (specifically couplers/pads placed underneath the vehicle)

Once you have the electronic system fitted, you can have the chemical spray applied and you’ll be protected both electronically and physically.

Conclusion:

We hope that this has given you a better understanding of your options for rust protection on your vehicle and a better outline of the costs, maintenance and other factors.

We should note that this assessment is given as an educational guide and all data and information based on our research and findings.

7 Practical Maintenance Tips For Aussie 4WD’ers

,

Is there anything more satisfying than packing all the gear, loading up the 4×4 and getting away from everyone and everything?!

 

If this sound like your ideal weekend, there’s a good chance you’re a fan of adventure! For most Australian 4WD owners, beach driving is one of the most pleasurable & accessible ways to enjoy your vehicle. However, often in amongst all the excitement we can overlook a key component of a good trip:

 

Maintenance

 

Looking after and maintaining your vehicle isn’t always exciting. Actually, most of the time it’s straight up boring! However, if you care about your vehicle’s longevity or making it back from your next trip, it’s important to think about all necessary procedures both before and after the getaway.


To help you on your next adventure, we’ve compiled a super simple and practical 7-step guide to help maintain your 4WD and keep it in top shape!

 

 

Maintaining and servicing your 4×4 can be a costly process; especially if you’re going off-road. Other issues to watch out for : heavy towing, badly fitted/poor quality parts breaking or malfunctioning, rough driving conditions (such as unsteady ground, river crossings, corrugated roads, sand or mud) and intense weather.

 

 

Although most of this information is common knowledge, we hope that it may jog your memory on your next trip or perhaps shed some light on a new technique for keeping maintenance costs and off-road troubles to a minimum.

 


 

Bonus Tips:

1. We always recommend to follow your vehicles service book recommendations regarding engine and oil specifications.

2. To prevent costly engine and/or fuel systems damage (due to contaminated fuel) – late model diesel’s can use an extra fuel filter fitted in the supply line.

Remember  – Prevention is better than cure…

From all the team, best of luck on your next adventure and stay safe!

Protecting the Aussie dream – Creek to Coast

,

 

If you’re a fan of this show (Creek to Coast), chances are you’ve thought about loading up the van, hitching it up to the car and taking off around the country. It’s the great Australian dream. Now plenty of people talk about doing it, not that many people actually get around to doing it. We’re about to meet a man who’s put his money where his mouth is.

 

 

Paul Gibson is definitely what you’d call a silver lining kind of bloke. Even in a summer downpour, he’s still got a smile on his face. And why wouldn’t he! Travelling the country with the 5th-wheeler hitched up, and his wife Sandy by his side – it’s a setup and lifestyle that plenty of people would envy.

 

 

Paul and Sandy are making the most of retirement and have the pics to prove it. They’ve spent the majority of the last 6 years on the road, and aren’t showing any signs of settling down anytime soon. I was just having a look at some of these photos and I saw the rig, fully complete. You’ve got the tinny on the top of the truck…

 

‘There’s two things in life you’ve gotta take with you – the cook is number 1 and the tinny is number 2!

 

– Paul Gibson, Ex-Commercial Fisherman

 


For people contemplating that wandering lifestyle, what would you say to them?

 

‘Um, what would I say – I would say…that there’s a goal to look forward to and don’t leave it too late! I should’ve retired 5 years earlier.

 

 

For Paul, it’s a well earned reward for 35 years working as a pro fisherman on the Gold Coast. I was looking at some of this vision before, this is you catching fish on the beach is it? ‘Yeah that’s correct’

 

It’s a job that’s the very definition of tough on the gear. In fact, he reckons you’d only get about 2 years out of a truck, before it was time to trade it in for a new one…that was before he was introduced to a thing called ERPS – Electronic Rust Prevention System.

 

Previous to putting electronic rust prevention in my vehicles, when we’d take the vehicles to trade them in, the dealership wouldn’t want to know us.

 


 They’d say, if you took it to a farm you might get $2000 for it, if you’re lucky ! But since I was introduced to this electronic rust prevention, the first 2 1/2 years we had the vehicle, I took it in and the guy says

 

“Aw jeez, it’s not a bad looking vehicle – I might have to give you about $20-22,000”

 

– I nearly fell off the chair!’


After 20 years of field testing, he’s now a convert. In fact, he’s got an ERPS installed on both of their Land Cruisers. Sandy’s 100 Series and the tow-car, Paul’s custom dual-axle Cruiser Ute. It’s quite a technical system, even Paul admits he doesn’t really know how it works. But he’s seen firsthand the difference it makes – and that’s enough for him. There’s an Electronic Rust Prevention System to suit just about every vehicle and application.

Beach Driving with Channel 7’s, Andrew Mirosch (Creek to Coast)

,

Driving on the beach is one of the few off-road challenges suitable for just about any SUV or 4×4. Beach driving is fantastic fun, but be aware, there are a few dangers lurking…

 

 

It can be hard avoiding salt water, it rises up from the sand as you drive, sea spray can cover your car and if you’re driving into the sea, well, you are doing something wrong!

 

Water + Salt + Sand = Rust

Rust is iron oxide – it’s the product of an electro-chemical reaction known as corrosion.


So what is ERPS?

‘This little generator here is the heart and soul of our Electronic Rust Prevention System. It’s a system that is designed to put a charge through and protect the vehicle from rust. That’s your insurance policy – protecting your vehicle.

Obviously here in Australia we’re absolutely spoilt for choice with the locations we can go to; the beach lifestyle. There’s consequences of that obviously, when you’re on the beach, you’ve got salt and you got moisture, water – and that’s always looking to attack your car’

-Jeff Eastwood, managing director ERPS


 

But you’ve still got to care for the car, you’ve got to wash it down and do all the usual things we do when we come off the beach as well?

‘Absolutely, all the normal maintenance – wash your car thoroughly with good clean water and get the salt and the sand out of it as much as you can…but obviously you can never get it 100% right’

 


But you also do other things? It’s not all about cars is it?

‘No, we’ve strangely enough done everything from grand pianos to 400 tonne crawler cranes, mining equipment, even locker systems at water parks’

 

 

Well this is it, isn’t it – the great Aussie dream!

‘Yes, living the dream! We’re out and about enjoying it and this is the lifestyle we’re trying to protect. About 98% of our product is built in-house. We do right from the design, through to testing and the manufacturing in our own facility’

 

So these were designed by us, they’re actually completely injected with silicon to seal it 100% and keeps all the moisture out. We do the same thing with our coupler pads, which is where the electrical charge is transferred to the body of the car. Again, they’re put in the press in the factory and injected with silicon.



With all of these components we use marine grade wiring because it stands up to the salt conditions better.

 

 

Even the fuses, because we design it ourselves, we’ve designed a small LED light into the end of the fuse which means if the fuse blows the light comes on. It’s a simple thing, but it makes a difference.

 

 

This is the heart and soul of our system. It transfers the charge to what we call the coupler pads and puts the charge into the body of the vehicle. There’s several things we need to get right with this: low battery draw, high voltage output, but no interference to the vehicle or the people in it.

 

 

What a fantastic day on the beach. You bought the snacks, I’m going to supply the fish and chips – and of course, extra salt!

Tips to tackle river crossings, with Roger Vickery

,

No matter what the weather forecast says, it’s important to make your 4×4 waterproof. Expose your vehicle to river crossings, beach driving or acid rain – you’re going to give rust a chance to get a toe-hold. The best protection you can give your vehicle before attempting a water crossing is to actually walk through it before the vehicle. That way, you know how deep it is and what’s on the bottom.

 

 

No matter how much mud and water you intend on exposing your vehicle to, it’s a great idea to get an ERPS – an Electronic Rust Prevention System. It guarantees to make the car safe from rust, and keeping it in prime condition for years to come.
