OBJECTIVE:
To Write a one-pager about Under-Body Coating and its purpose, its types in detail, and its pros and cons with the help of articles on underbody coating and research on interne.
ABOUT UNDERBODY COATING:
Underbody coating is a thick cladding (typically made of rubber) that is placed uniformly to the car’s underside. When the automobile is fresh off the lot and spotless, it is usually sprayed or painted on. But it’s acceptable if you apply the undercoating after a couple of years. This is because it might protect the undercarriage from additional harm.
TYPES OF UNDERBODY COATING:
Rubberized Underbody Coating:
This is generally thought of as the best underbody coating for your car. It preserves the underbody well, protecting it from scratches. Applying this to the undercarriage is not much of a hassle either. This can be done at the authorized service center or by the local repair shop at a reasonable price. Rubberized coating is ideal if you want to keep the road noise to a minimum and rust and corrosion away.
Wax Based Underbody Coating:
This – more or less – ephemeral undercoating will wear away in a few months’ time. On the upside, wax-based undercoating puts up a big fight against moisture. It is also the most affordable option out there. On the plus side, wax-based undercoating is resistant to dampness.
Asphalt Based Automotive Undercoating:
Best suited for lorries, trucks and large vehicles this provides a greater degree of protection compared to rubber-based coatings. However, asphalt-based coatings contain little amounts of rubber for sound-insulation purposes. The process of applying this coating is a bit time-consuming though.
Polyurethane Underbody Coating:
This coating closes up splits and fractures on the underbody of the vehicle. It offers up good protection against corrosion and also bonds with the metal. Unlike in the case of asphalt-based coating, you can paint over the polyurethane coating. This covering seal breaks and fractures in the vehicle’s underbody. It provides strong corrosion resistance and also binds to the metal. Unlike an asphalt-based coating, the polyurethane coating may be painted over.
PROCESS OF UNDERBODY COATING-
When it comes to updating your vehicle or using any sort of coating, remove the rust completely first and then proceed. Rust removal is easily achieved by sandblasting or sanding, depending on the area and the extent of the rust.
Once you've removed the rust and prepped your undercarriage for coating, give it a quick rinse and let it dry to ensure you aren't further trapping any contaminants on your vehicle's underbelly. Using a degreaser to clean the metal first is also recommended.
Most undercoating is generally applied with a spray gun. A disposable spray gun will work best; once the undercoating hardens, it becomes very difficult to clean the gun even with a lot of thinner. A Schutz disposable spray gun is the best option.
No matter what type of vehicle undercoating you've selected, two coats will provide the optimum protection. Allow ample dry time between coats.
Let the undercoating cure completely (usually overnight) before driving your vehicle on the road.
DISADVANTAGES OF AN UNDERCOATING
It is less helpful if corrosion is already present:
For an undercoating to be the most effective, it should be in place before the underbelly of your car begins to rust. If you apply it over corrosion, you will still isolate the metal from further moisture and airflow, which is good, but the existing oxidizing/rusting process will still continue to occur. After rust is already present, applying an undercoating will slow the continuation of the corrosion process and will make your vehicle look better… until the rust breaks its way through the layer of undercoating you’ve applied. If you have rust present, it is better to remove the rust and then apply the undercoating.
It works best on new cars:
If you’ve purchased a used vehicle, then the cost of preparing the underbelly for an undercoating might be more than the value of the car. You must remove all the residue from the bottom before it can be applied. Failing to do so will seal in the debris that is present already, which can lead to more problems. The best time to have an undercoating applied is when a vehicle is purchased new because it offers a superior level of protection then.
A third-party undercoating service might void your vehicle’s warranty:
Some new cars no longer need the undercoating service provided because the structure of the vehicle has it built-in already. If you hire a third-party provider to apply an undercoating, you could void the corrosion-perforation warranty that is factory-provided. Most vehicles today that leave the factory floor are all provided with included rust-proofing.
An undercoating is not impervious to damage:
An undercoating can provide a hardened layer of protection against dirt and debris that may cause corrosion. Depending on where you drive, however, the lifespan of this product may be minimal. If you drive your vehicle on gravel roads or dirty areas frequently, you reduce the integrity of the protective layer. You might find that your undercoating begins to chip off in as little as 25,000 miles because of this issue. Driving in a salty environment is not the only threat to the integrity of this product.
It must be reapplied every 3 to 5 years for the best results:
The only way for an undercoating to provide ongoing protection for your vehicle is to have the service repeated frequently. Most owners can have a new layer applied in about 5 years without worrying about their underbelly being compromised. In salty or destructive environments, however, you may need to have a new undercoating applied every 3 years for the best results.
ADVANTAGES:
Fights Rust:
It has a crucial function in preventing corrosion. Underbody coating is particularly useful if you live near the sea, where there is excessive humidity and rust is a common occurrence. If you live somewhere where it snows in the winter, you should seriously consider undercoating. During the monsoon season, cars are at high risk of getting corrosion. If you want to extend your car’s life you should get an underbody coating.
Absorbs Noise:
Very strong undercoating, realize it or not, can attenuate noises that enter the cabin. The undercoating, which is frequently made of rubber, absorbs part of the rackets. The car’s occupants could avoid the road sounds — at least to some extent. So if you want a quite ride and pleasant experience it is always a good idea to consider getting an underbody coating
Reinforcement:
If your automobile already has an underbody covering, applying another one on top of it will not harm it. It will provide further protection for the underbody from water, road debris, gravel, and tiny stones. The factory coat would also have a lower risk of flaking away.
Prolong Car’s Life:
A good undercoat protects not just the underbody from corrosion, but also the engine and gearbox! Less corrosion combined with slower wear and tear can extend the life of your car by many years. On the undercarriage, there would be fewer dents, dings, and scratches to worry about.
CONCLUSION:
The pros and cons of a vehicle undercoating offer a complex opportunity to protect some new and used cars, but not all new vehicles require it. You must perform your own due diligence on a vehicle you’re wanting to purchase to decide if this service is right for you. And, if the cost is an issue, it is possible to apply your own undercoating, though such an action might void an active warranty.
Underbody coating is one of the hidden factors for prolonged life of the car. As it protects the car from dust, minor hit of small gravel, minor wear and tear and rust. It provides strength to the underbody. But the coating is not for lifetime, it removes or chipped out as time passes. In wet area, the coating damages faster as compared to dry area. So therefore, check-up is required over every 2 or 3 years.
