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.
Choosing to forego rust proofing can result in more repairs more often, adding to the overall cost of your vehicle’s lifespan.

He suggests rust proofing your vehicle before you leave, and explains that it can be done right at the dealership, for a fee. We’ve done some research on four of the most common rust proofing methods to make that decision a little easier.
Photo: Shutterstock One of the newest and most heavily disputed methods of rust proofing is through an electronic rust protection system. Often sold by your dealer, an electronic module is a small device that must be professionally installed in your vehicle.
These systems emit a weak current through a vehicle’s metal body, theoretically preventing it from reacting with oxygen and corroding. Photo: Shutterstock Also known as an “undercoating,” tar-based sprays were initially introduced in the 1950s to make car rides quieter.
The procedure involves spraying a black, tar-like substance on the floor pans, wheel wells, and other exposed parts of the under body of your car, which then hardens and acts as a permanent shield against moisture, salt, and other elements. Unfortunately, over time moisture can seep behind the hard outer seal and corrode the metal beneath.
Furthermore, the rigid nature of a tar based spray makes it susceptible to cracks, which will pose an entrance for water to get in. Compared to its tar-based counterpart, a dripless oil spray covers more surface area because it’s applied to more interior regions of the vehicle, but this added protection comes with a price.
The application process often involves drilling holes into the frame of the vehicle to maximize the area covered. Additionally, these sprays will often leave smaller crevices and tight seams on your vehicle unprotected because of their high viscosity.
The biggest knock on this method is that the sprayed oil will drip off your vehicle for about two days as it dries. To make matters even more complicated, it’s become a common practice for manufacturers to use galvanized steel in their vehicles frames.
With a coating of zinc, galvanized steel doesn’t react with oxygen the way iron does greatly reduce the risk of rust. Rust proofing will make more sense if your vehicle is regularly subjected to the elements, but if you plan to mainly do city driving in a warm climate changes are it isn’t necessary.
Those with a short-term lease won’t see much benefit in rust proofing, save for a slightly higher residual value. Rust proofing and undercoating are excellent examples of an automotive service that’s not usually heard of but is essential for better safety and protection.
But, if you want to practice excellent car care and ensure that you can make the most out of your ride by giving it the best love possible, auto rustproofing is a procedure you would have to do. The first thing you need to understand is that rust forms on your car the moment you drive it out of the dealership.
Since you drive your car in an environment that’s already full of these elements, it is inevitable that your ride will accumulate rust. The great news is that the global auto industry has already created automotive technology that can give your auto a good quality barrier through products like rust inhibitors and rust converters.
Brands like Rust Check are already well-known because they use quality chemicals to give optimum performance. This is made harder by the fact that not many people know the difference between rust proofing vs. undercoating.
Contrary to popular belief, they aren’t synonymous and you can save a lot of time by learning how they’re both different! But you must not forget the interior surfaces of your car’s hood and doors since rust can oxidize from there as well.
You must know its main function to fully understand and appreciate why undercoating is still needed by your car. Undercoating is the sprayed application of a wax or rubber-based composite onto the entire underside of the vehicle.
It’s designed to create a rust -proof layer between the underside of the vehicle and the water, ice, and salt of the road. Give it a year tops and you should probably remove your old undercoating and apply a fresh new layer.
Even if your car’s underside isn’t actually visible, it’s still very susceptible to damage when you go out driving. Applying an undercoat to a vehicle plus curing time usually only takes a single day, so long as sufficient time is given for the applied coating to fully dry and adhere to the vehicle.
Mud, dirt, debris, rainwater among many other pollutants can cause you problems in the long run. By applying undercoating, you’ll get maximum rust protection and you wouldn’t have to worry about a while.
Therefore, combining the undercoating or rustproofing could provide the best of both worlds of rust protection for your vehicles. Also, it’s highly recommended doing an undercoating if your driving commute involves a lot of distances over salt-soaked highways as salt increases the speed of corrosion.

This product also has sound deadening properties that can help reduce road noise when driving. Heart International Corporation is one of the very first companies to introduce rust proofing to the world.
In fact, they have a very long and rich history already and can be considered pioneers and experts in rust proofing. Heart products can be traced back to 1959 when Kurt Heart, Rudy Herman, and Joe Sewage first decided to open their rust proofing shop in Detroit.
Although many people considered their innovative product to be a hoax at first, the quality and performance were undeniable. Another great company to look into when searching for excellent rust proofing and undercoating shops is Known (see this post for a mother that talks highly about this brand).
Their amazing products are highly innovative and this company continually gives importance to research and development so you know you’re getting only the best and most recent technology there is. This company is also known for its Known rustproofing warranty, a testimony that they also care what their customers think.
Well, to give you a ball-park estimate, a typical rust proofing service will be available for about $125 to $200. The reason for this is that most parts of your undercarriage are made of galvanized steel coated with zinc.
But the keyword there is “less likely.” There are instances that the zinc can get chipped off and then your ride will be left unprotected. This tar act as a barrier to guard against moisture, salt, and other substances that can cause rust.
Though you can purchase off the shelf undercoating and rust proofing spray and DIY but getting a professional to do is better to ensure it’s done properly. Electronic method Using a weak electric current, this small device can stop the corroding effects of rust.
So far, the electronic method does work for water automobiles but for land vehicle, it still remains uncertain. Dripless oil spray A wax-like substance applied to the entire body of the vehicle, it hardens once it has dried.
After removing any rust, it is time to prime and paint the underside of the vehicle. The last step in the process requires you to apply an undercoating to the under body of your vehicle.
