Underbody Coating
Underbody Coating
About
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.
Corrosion usuall happens when the outer metal surface is in directly exposed to moisture and oxygen which results in the oxidizing of the metals and can easy destroy the condition as well as the life of the vehicle, so in order to prevent that, a layer of coating is done on the body of the vehicle to prevent direct exposure of the surface to the atmosphere.
Types
1. Wax or Paraffin-based Undercoating
When choosing an undercoating, the lanolin approach remains a proven, if not slightly strange solution. Commercially, lanolin coatings are used as both a rustproof coating and as a lubricant, with everything from ship hulls and rigging equipment, to heavy-duty excavation machines and production facilities relying upon this water-repelling corrosion inhibitor.
When it’s sprayed, lanolin fills in all of the nooks and crannies of the chassis with a sticky, wax-like substance. Curing times will vary depending upon air temperature and how heavy of a coating has been applied, so there will likely be some downtime between car rides after this stuff has been sprayed.
2. Rubberized Undercoating
Ideal for cars driven in rough terrain, as its name suggests, this undercarriage coating involves applying a rubber agent to the underbelly to protect and cushion it against dents, dust, and moisture.
It can also be applied around wheel wells and quarter panels. Considered the best option for standard vehicles when it comes to the different types of undercoating.
3. Polyurethane Undercoating
Uses a polyurethane-based sealant that comes in canisters ready to be loaded into a spray gun and sprayed to guard the undercarriage of your vehicle.
The polyurethane used in this product is a high-quality and durable material that is perfect for any weather condition. It is ideal for standard vehicles.
4.Asphalt-Based Undercoating
It reportedly has the most damage-resistant properties. Although asphalt-based undercoating is ideal for trucks, military, and all-terrain vehicles, it will also help protect your car, truck, motorcycle, and heavy machinery from the elements.
It last long and is best for endurance vehicles that have to undergo heavy road use.
When it comes to large trucks, heavy machinery, military, and all-terrain vehicles, asphalt-based undercoating provides added durability against rocks, chips, and moisture.
Advantages
1. It provides a layer of protection against corrosion.
When an undercoating is properly applied to a vehicle, then you’ll be providing the underbelly with a layer of protection against rust and 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.
2. 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. Even your transmission and engine have exposure to rust when there isn’t a vehicle undercoating applied.
3. Reinforcement
If your car comes with stock underbody coating, using another coating on top of it, is not going to hurt. It will offer additional reinforcement, protecting the underbody from water, road debris, gravel and small pebbles. There would also be a lesser chance for the factory coat to flake away.
4. Absorbs Noise
A very thick undercoating can soften the noises that reach the cabin. Since the undercoating is often made up of rubber it absorbs some of the rackets. The occupants of the car could spare themselves of the road noises – at least up to a certain extend.
Disdavantages
1. 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.
2. 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.
3. Most vehicles make it five years before corrosion begins to show.
For vehicle owners who purchase something new every 3 to 5 years, then rustproofing may not be a good use of your cash. Although an undercoating does add value to a used car, that only applies when the rustproofing product used provides a transferrable lifetime warranty. Most vehicles that are on the road today are able to make it five years before any corrosion begins to show. It may be 7 to 10 years before the functionality of the vehicle is negatively impacted by the lack of an undercoating.
4. It adds weight to the vehicle.
Although the amount of weight added to a vehicle with an undercoating is minimal (between 10 to 20 pounds for most vehicles), there is a small element of fuel economy to consider. When your vehicle weighs more, the distance you can travel on a single tank of fuel is reduced. The undercoating might reduce your efficiency by up to one mile per gallon, which creates a small additional fuel cost over time. Still, the effect on mileage of this additional weight is negligible compared to the effect a driver can have by the way they drive.
5. 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.
