Undercoat or not

Undercoating and rust-proofing are examples of offering protection and care to the underbelly of your vehicle. Even if you live in a warm climate where salt or ice-melting chemicals are not used on roadways, it is essential to protect against corrosion and rust on the underside of the car, truck, or SUV.

Even though the terms are used interchangeably, an undercoating applies to the exterior of the vehicle. Rust-proofing goes inside the vehicle. All the moving parts underneath the vehicle must work in harmony to ensure your driving experience is safe. That is why a vehicle undercoating provides you with the safety and functionality you need over a long-term basis.

It provides a layer of protection against corrosion. Instead of contacting the metal components of the vehicle, the debris encounters the undercoating, which then proactively repels the dangerous items away.

Although an undercoating will eventually wear out, it can provide years of protection against premature corrosion. It will extend the life of your vehicle.

A proper undercoating extends the life of your vehicle because of its rust-stopping power. Corrosion does more than affect the integrity of the metals in your vehicle. It can get into your metal wires and cables, affecting any component which is comprised of steel or aluminum. It can be applied to damaged areas. Over time, the underbelly of your vehicle is going to develop nicks, chips, and scratches because of the debris you encounter while driving.

Unlike older forms of undercoating, which included the use of asphalt and animal fat, modern products provide a real layer of protection because it can morph into the various areas of small damage. A modern undercoating is usually wax-based, which creates a living barrier that your vehicle can use to promote a self-healing experience. It can be self-applied. Rustproofing works best when you have this service professionally applied to your vehicle. If money is tight, however, and you have some basic car maintenance skills, then you can do the work yourself.

Some dealers include it in a package of services that are priced even higher. There are multiple undercoating methods that can be used. There are four different undercoating methods that are commonly used on vehicles that require this service. The electronic method is used when rust is present to stop its corrosive effect, which is a method that receives mixed reviews.We usually write blogs to our entire audience — but this one is truly a northern-focused article.

And for those who deal with arctic climates or live in areas that frequently use road salt or mag chloride, it can be a lifesaver to protect the undercarriage of your daily driver. The question we need to address though is whether these products are still needed.

But road warriors of today are constructed from aluminum, polycarbonate materials, and other exotic materials that are less susceptible to contaminants. We will also introduce a few of the best products on the market today. Table of Contents What is an Undercoating? What are the Different Methods to Apply Undercoating?

How Does Undercoating Protect from Rust?

Wrapping it Up. The undercoating is sprayed on the chassis and is marketed and advertised to customers as a rust protectant that also helps reduce road noise. They are both intended to protect the vehicle from corrosion and developing rust. An undercoating is a sprayed-on accessory, that protects the materials underneath the vehicle.

Rustproofing is a process that involves the application of protective waxes or other coatings on other areas that are made of corrosion-prone materials on the outside of the vehicle. Rust protection is a manufacturing process that adds ingredients that acts as a rust-inhibitor.

A rust inhibitor helps to block the circulation of electrical current — which is a critical component in the development of rust. Plus, more and more daily drivers are using materials like Aluminum that naturally resist the development of rust. The most common method of dealer-applied undercoating is via the spray. This method involves removing the electrical current capacity of items underneath the vehicle.

It circulates a weak electrical current through the materials, which reduces the potential of corrosion. Drip oil spray is an incredibly messy, but very effective method of protecting the undercarriage. The problem is it takes a long time to cure. The final option is dripless oil spray. This is a wax-like substance that will be applied to the entire vehicle body and undercarriage to provide a rather strong layer of protection but can wear thin sooner than other traditional methods.

A few weeks ago, we wrote an article about rust protection and how ceramic coatings help reduce the potential of rust build-up.

In that article, we outlined the science behind what causes rust. When metal corrodes, electrolytes supply the fuel or oxygen in this case to the anode. As oxygen is introduced to the metal, electrons are freed.

Does Your Car Need Undercoating?

As they move to the cathode, metal on the anode vanishes and is converted into rust. The coating solutions will block the electrolyte from penetrating the metallic surfaces. In most cases, this is either road salt, saltwater, or standard wastewater on the roads. The electrical method explained above helps to block the anode from circulating electrons. This is typically a permanent solution that does not need to be repeated.Using improved processes, technologies and components they made great advances.

The use of zinc coated steels and electrostatic primers and the expanded use of seam sealers greatly reduced corrosion concerns.

We also saw an evolution of the metals used, from mild steel to high strength steel, ultra high strength and now boron steel. This evolution in materials has continued and is forecast to continue in future generations of new vehicles. These improvements emboldened vehicle manufacturers to extend their anti corrosion warranties from one year to three, five and even ten years against corrosion due to a defect in materials or manufacture. Perversely, successes brought about by these changes have led to the reemergence of the old auto nemesis, rust.

Couple that with the fact that owners are now keeping their vehicles longer than ever before and the introduction of new snow and ice control chemicals and you have a misinformed public operating in a corrosion risk rich environment. Road salt? Old news. Liquid calcium chloride and magnesium chloride are now the de-icing chemicals of choice. They are more effective but far, far more corrosive. Corrosion protection is important regardless of geography! Metal fatigue, paint refinishing, welding and time can cause these barriers to break down.

So, now this vehicle is in your shop for repairs, how are you going to protect the repairs against failure due to corrosion? Many paint and primer type applications promise to provide a corrosion barrier and do, to a point. This is why hem flanges and overlap flanges will often exhibit corrosion in as little as a year following a repair.

Cavity Wax and Undercoating products provide an inexpensive and effective corrosion barrier. Simple to install, these products can protect your repair and your reputation. Ford Motor Company and Chrysler LLC recognized this fact and in introduced their own brands of Cavity Wax and non-rubberized Undercoating, Motorcraft and Mopar respectively and now specify their use in both sheet metal and structural repairs.

These were products that withstood rigorous engineering review. All brands of cavity wax and undercoating type products are not created equally. In addition to Ford and Chrysler, other vehicle manufacturers are preparing to alter their collision repair procedures to include a stronger focus on rust protection. Some insurers, as well, are paying closer attention during inspections to the corrosion protection that they are being billed for. There are two areas that are typically treated, exposed areas and those areas that are enclosed or cavities.

Under Coat is used in areas that are easily accessible and exposed directly to the road, in other words the underbody and wheel wells of the vehicle. Under Coat not only protects against corrosion, it also has a sound deadening and cosmetic function.Welcome, Guest. Please login or register. Home Help Search Login Register.

Undercoating: The Good, The Bad, and The Rusty

Pages: [ 1 ] 2. Author Topic: Undercoat or not? Read times. Dannoc Piglet Posts: I have always undercoated, be it black, white or grey.

I've prepped a load of pp's British AWI infantry and thought I'd give a couple of figures a wash with GW nuln oil and wow did it bring out the details. My eye sight is not what it used to be and even with glasses and an illuminated magnifier I can't see this much detail. So what am I'm thinking - undercoat or not?

Does anyone else leave off the undercoat? Thanks guys. Dannoc, I would suggest one should always prime having washed the castings following cleaning to remove swarf and grease, of courseas I believe that it helps the paint adhere better and thus last longer.

Some may prime and then undercoat. I do like the look of the casting with a wash and I always use a wash of some kind after the base colours, as I'm too clumsy to shade properly and it brings out the sculpting very well. You may wish to consider a light coat of white primer followed by your Nuln Oil wash before you start painting proper, to get the best of both worlds?

I am interested in hearing what others think. I've always undercoated in white, as my eyes lose the detail if I use black. As I am about to start a new project PBI partisans I will try the white undercoat followed by a contrast wash and see how I get on. Due to my aversion to black and my excessive stock of other wash shades though I will use a brown or green. I'll let you know the results in a couple of weeks.

Always prime my bare metal and plastic. The paint formulated as primer is to provide a key for the undercoat and top coat. If I forget an odd figure and try to paint with out priming then the metal will show through on some edges.

New cars come from the factory already coated underneath with a variety of coatings that are designed to protect the chassis from such things as rust, salt and oil.

Whatever the dealer tells you, undercoating is not primarily a rust preventative. Undercoating is designed to deaden road noise and to make the interior quieter, not to protect from rust. The undercoating material is too thick to get into tiny crevices where moisture can collect.

Undercoating can even clog up drain holes in the frame that are designed to drain water from areas where it might collect.

While undercoating will prevent some rust, it must be applied when the car is new and the chassis is perfectly clean. As a result, severe rust on a car is very rare. Unless you are in an area where a lot of salt is used to clear the roads of ice and snow, undercoating is probably not necessary and can add significantly to the cost of your new car.

There are services like the rust proofing and undercoating but what is the difference between rust proofing vs. Some people might say that both services are redundant and just a waste of money. 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.

14 Vehicle Undercoating Pros and Cons

The first thing you need to understand is that rust forms on your car the moment you drive it out of the dealership. Just mix iron, oxygen, and water and voila! Rust exists. The only thing left to do is to provide some type of structural protection to it. Check out the video below. 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.

But with all these, advertising for these products can still be confusing. This is made harder by the fact that not many people know the difference between rust proofing vs. Some parts of your autobody can easily be protected but others still are not. These are done by spraying a kind of protective wax all over parts that can easily chip or where moisture can accumulate. 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.

Did you know that your vehicle is already equipped with some undercoating when you buy it from your dealer? Give it a year tops and you should probably remove your old undercoating and apply a fresh new layer.

Undercoating is applying a protective layer in the undercarriage of your ride. This includes the floorboards, wheel wells, and frame. 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.

If you want to know if your vehicle needs any of the two services, you can always ask your local mechanic. When it comes to comparing both methods, the needs of each customer will often determine which option is best for them.

For car owners who like to see a spotless exterior may gravitate more towards rust-proofing service instead of undercoating. These two treatments are far from mutually exclusive. In fact, they are excellent at complimenting each other.

Therefore, combining the undercoating or rustproofing could provide the best of both worlds of rust protection for your vehicles.
