Underbody Coating
UNDERBODY COATING
While we are sitting inside the car and enjoying the smooth ride, the underbody of our car is facing many obstacles that will definitely harm our car one day. The car is exposed to muddy water, stone, rugged roads, and potholes. This leads to have a serious issues if not taken care of.
We all are aware of the fact that the underbody of the previous models was made from durable metals such as steel, which is easily damaged and oxidized, forming rust. The speedy beast today is made up of polycarbonate material, aluminium, and other tough materials that are more stable against corrosion. Not to mention, car underbody treatments make them more durable.
Maintaining car underbody coating can be a lifesaver for the driver. Conventional underbody treatments such as road salt or mag chloride are still used for rust or corrosion-related issues.
What is Car Underbody Coating?
No matter the climate, the underbelly of every vehicle needs proper care and protection. Undercoating helps protect your vehicle against rust and corrosion.
Seals on the underbelly parts have gotten a lot tighter and more effective at keeping out dust and moisture, but there are other factors to consider. Poor roads, rocks getting thrown from the tires and denting the metal, and corrosion from road salt in the winter all play a huge part in the damage or decay of a vehicle's underbelly. Used vehicles especially will need a little underbelly protection -- while it's already been exposed to contaminants and rust, applying undercoating will prevent further damage.
Different Types of Vehicle Undercoating
- Rubberized Undercoating
Rubberized under coating is easy to apply and offers sound-cushioning as well as protection from dust, moisture, and dings or dents.
In addition to your undercarriage, rubberized undercoating is also safe to use on wheel wells and quarter panels, and dries to a soft rubbery finish that prevents further rust, damage, or moisture seeps. The coating can be painted over and, if necessary for bodywork, can be easily removed with an undercoating removal spray.
Overall, rubberized coating is generally the best option for protecting your vehicle's undercarriage, as it provides the simplest and best protective measures against rust and moisture.
- Polyurethane Undercoating
The other option for undercoating your vehicle is to use a polyurethane-based sealant. This type of vehicle undercoating is a little bit quicker and easier to apply.
Oftentimes, polyurethane undercoating will come in canisters ready to preload into an application gun. This type of sealant works by seeping into all cracks and seams, displacing salt and moisture and oozing around rusty areas to bond with and protect oxidized metal. It also sands quickly in case you'll need to perform bodywork and can be painted over.
On the flipside, this type of car undercoating generally requires a little bit more surface prep work before applying -- sanding and applying an etching primer to bare metals before using are generally recommended.
- Wax or Paraffin-Based Undercoating
A paraffin-based undercoating will be the cheapest and quickest option available with which to protect the undercarriage of your vehicle. However, keep in mind that it will wear off quicker than other types of undercoating and will need to be stripped and reapplied at least once every year.
Wax-based undercoating never truly harden. During application, they drip or flow into seams and cracks to provide protective properties. They are usually available in a spray gun canister or in an aerosol can and offer at least a base protection in moderately humid climates.
- Asphalt-Based Undercoating
For standard vehicles, any of the aforementioned types of undercoating will provide sufficient protection. For large trucks and heavy machinery, asphalt-based undercoating provides a bit of extra durability against rocks, chips, and moisture.
Asphalt-based undercoating generally contains a little bit of rubberized material that sets up firmly and also helps soften noise. Generally sold in five gallon containers, this type of undercoating also needs more cure time than the other three, and is NOT paintable, making it best to use only for undercarriages.
How Does Undercoating Protect Your Vehicle From Rust?
To understand the science behind how undercoating protects the vehicle from rusting, we should know about rusting first.
Rusting occurs when the current passes through anode to the cathode through the electrolyte.
The electrolyte provides the fuel, which is oxygen in this case, to the anode. Oxygen reacts with the anode, releasing some electrons free. The electrons move from the electrolyte to cathode. The metal at anode starts disappearing and depositing as rust. This rusting of iron or steel results in corrosion.
Pros
- It extends the life of car
The protection against rusting gives the biggest advantage, which is the long-life of the vehicle. If undercoating is done the right way, then it will provide protection for up to 10 years. In some cases, the time span is more than ten years, which extends the life of your vehicle.
- Reduces road noise
The undercoating serves as an extra layer of insulation, reducing the noise from penetrating inside components. Thus padding acts as a barrier between you and the source of the noise. If the road noise bothers you while driving your car’s then applying the undercoat can help you.
Cons
The main disadvantage of the under body coating is its cost. The cost of Underbody Coating has reduced over the year but it is still expensive. But it is nothing in front of replacing the car. May be it is too expensive but in my opinion we should apply the Underbody Coating to our car.
