To get a good price for their vehicle, the owner takes careful measures to ensure its longevity, such as guarding against corrosion from rust. Although many vehicles these days are manufactured with corrosion protection, there are a range of aftermarket kits to rustproof the car once the factory-made product has grown weak.
This little device can be easily installed by a mechanic, and works by issuing a weak electric current throughout the metal of the vehicle. While rustproofing your vehicle is definitely encouraged, sprays and waxes are often the more recommended options, and have been proven to work over the years.
Experts pursuing automotive careers do not believe there is substantial evidence regarding the efficiency of an electronic rustproofing system, or that it works better than other options like waxes. In addition, the cost of repairing the damage done by any corrosion that develops can really add up depending on what component(s) are affected (paint, circuits, floor panels, etc.
One of the best ways to protect your vehicle and ensure you maintain its market value is to apply a rust proofing solution. The process involves spraying a rust proofing product on the surface of the under body that is designed to protect it from moisture.
These solutions seep into the hard-to-reach door seam, joints, and crevices that are hotspots for rust and corrosion. Small holes need to be drilled in order for the product to reach certain areas of the car (more about this later), and an annual application is typically recommended.
This product is designed to prevent corrosion on the entire vehicle, and won’t cause any dripping after application. This solution involves an electronic module that sends weak electric currents through the metal of a vehicle.
This is a great short term solution, however the undercoating can chip away and cause moisture to actually seep into cracks, getting trapped under the coat and accelerating the corrosion process. The undercoating also doesn’t protect the rest of the car, and won’t be any help for areas already affected by rust or damage.
When done by a trusted professional, any holes should be drilled in unnoticeable places such as near the door latch and on the underside of the vehicle, and will be too tiny to spot. The benefits of drilling in order to apply a rust proofing solution outweigh the inconvenience of having small holes that no one will ever know are there.
Other elements such as dry weather and the UV rays from the sun can accelerate rust and corrosion once the initial damage occurs. In winter conditions, salt and other chemicals used for snow or ice removal make its way underneath your car and stick to the metal surfaces.
The combination of salt and water is more damaging than rust, as the solution eats away at the metal, weakening it and causing it to fall apart. Salt and deicing chemicals are designed to lower the freezing point of water, allowing your car to hit pavement in winter conditions.
Electronic protection works IF you drive into water to ground your car. The cars themselves are part electric, so electronic rust proofing seems to make even more sense.
Corrosion research has found that cathodic protection can slow rust … but on boats, NOT CARS. For electronic rust proofing to work, you need a completed circuit of protective electrons.
“The only way to complete the circuit on all metal in your car is to drive into seawater or to be buried in soil!” (Corrosion-doctors.org). That’s why cathodic protection isn’t proven to work for cars.
In fact, corrosion engineers warn consumers to watch for fraudulent gadgets such as cathodic protection of automobiles * (National Association of Corrosion Engineers Materials Performance Magazine). To stop the sale of these “pseudo-scientific” gadgets in the past, court orders were issued in Canada and the U.S.
The Globe and Mail says Electronic rust protectors will eat a hole through your wallet and probably won’t protect your vehicle any more than it’s protected already” in this article Globe and Mail Article March 2012. Interestingly, Chad Heard of Hyundai Canada is of the opinion that after-market electronic rust prevention is unnecessary.
So auto manufacturers themselves may not recommend the dealers’ aftermarket electronic rust proofing! The seams, cracks, nooks & crannies are typically in good shape.
Cars that have not been rust proofed or have that scam electronic thing on it do not come apart with ease. Apparently Team Chrysler fitted this to my wife’s car about 7 years ago when it was new, along with an under body seal.
This unit I only found recently, and didn’t know what it was, after removing the battery to check what this flashing red light was, I laughed. There is a 5 year g’tee so this is well over, this device is pure snake oil.
If electronic protection worked, we would be happy to sell it and make a profit. It could be a big waste of your money and be very disappointing in the long run.
(Note: If your new car or used car already has an electronic module installed, scientifically proven Rust Check rust proofing can give you effective protection without affecting the module.) For 30 years proof on real world cars and trucks, take look at our customer testimonials.
I was looking into the Hyundai Kong EV before, and I was told specifically not to do any form of rust proofing! I was asked when I met with the financial manager, which we went through extended warranty and electronic rust protection.
From Canadian Tire, which is Canada based hardware store with automotive service, they have a similar module for about $350 before installation. Rust proofing, pin stripe, fabric protector, VIN etching, UV... All sales gimmicks by finance manager trying to get a dollar extra out of you.
These Cathodic Protection system do work under certain conditions, most notable is the requirement that the car be submerged in water (buried in wet soil is an acceptable alternative). If corrosion when your car is underwater or buried is a concern, this device will likely be worth paying for.
Living in the Sun Belt, you see cars 20-30 years old with faded paint for sure, but zero rust. Search for articles online from reputable websites, but I've always been told/read that the factory does a pretty decent of rust -proofing.
Nearly all modern vehicles are built with sophisticated corrosion protection, which makes rust -proofing obsolete in many geographical locations. However, warranty does expire and there are still plenty of regions in the world where vehicles are at a high risk of corrosion damage.
If you often drive in central or eastern parts Canada, then your vehicle may be at risk of rust due to heavy usage of road salts and plentiful snowfalls. Cars have changed a lot in the past 20 years, and one key difference is the treatment and usage of metal.
Modern car frames are galvanized and well-protected, which means that you can still drive your “ugly” vehicle without any major problems. If you want a cheap prevention solution, simply wash your vehicle after it’s been exposed to deteriorating elements, such as salt, and you should be good to go.
One rust -proofing method exists in the form of an electronic module, a device that sends a faint electric current through the sheet metal and generates an electrochemical reaction that stops the corrosion. These modules are easy to install, and many dealers offer them as an optional upgrade.
Electronic modules are designed to prevent rust and can also be found in retailers such as Canadian Tire. Simply put, the spray is an undercoating that creates a barrier underneath your car.
Also, take into consideration that you’ll need to bring your vehicle in for occasional check-ups to ensure there are no cracks in the barrier. But it does require extra steps, such as drilling holes into parts of the car, so that the substance could be applied.
The average price for dripless oil spray from Heart is about $120 to $140, depending on your vehicle. If you intend to trade in your vehicle after the warranty has expired, paying more for rust -proofing would be a complete waste of resources.
