Underbody Coating
UNDERBODY COATING
What is Underbody Coating ?
Underbody coating provides long term protection from corrosion to the car's underbody. It also protects parts like internal body panels, frame rails and other inner activities that are not physically accessible but are prone to corrosion.
Why Use ?
The main reason for cheating underbody coating is to prevent rusting and corrosion.The is not only required during the monsoon season but also in hot and humid climatic conditions. The coating is also must if you tend to live in coastal regions where the humidity in these areas speeds up the process of corrosion. This can be eliminated by asking your car service professional to apply a rubberised anti-rusting coat on your car’s underbelly.
Being in a country where not all roads are smooth enough and are filled with potholes, stones, debris, and uneven road leveling, the underbody coating prevents and absorbs all noise created by the contact of the surface of the road and the car by minimizing this.
When your car travels at high speed on the highway, the stones and debris hit your car’s underbody in this process and may lead to chipping of the underbody paint. Hence , it is advisable to have a thick layer of underbody coating to prevent paint from chipping.
The car underneath holds vital components like the silencer, engine, and numerous other wise and small engine components for different purposes in the cars. The cars underneath cannot simply be led to corrosion and further damage due to the car being driven during any weather condition. To avoid further major issues, the anti rust coating is a must for the underbody. This is again extremely important if you are living in an all-year monsoon or moderately high rainy regions as underbody coating is highly necessary for these situations.
Different Types of Underbody Coating :-
Having underbody coating professionally applied to your vehicle can be expensive, but fortunately. If your budget is tight, you can do it yourself for a fraction of the price. Here are some of the various types of underbody coating.
Rubberized Underbody Coating
Rubberized vehicle underbody 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 underbody coating is also safe to use on wheel wells and quarter panels, and dries to a soft rubbery finish that prevents further rus, damage, or moisture seeps. The coating can be painted over and,if necessary for bodywork, can be easily removed with an underbody coating 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 Underbody Coating
The other option for underbody coating your vehicle is a Polyurethane based coating. This type of vehicle underbody coating is a little bit quicker and easier to apply.
Oftentimes, polyurethane underbody coating will come in canisters read to preload into an application gun.This type of coating works by seeping into all cracks and aams, displacing slt and moisture and oozing around rusty areas to bond with and protect unoxidized 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 underbody coating 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 Underbodycoatings
A paraffin-based underbody coating 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 underbody coating and will need to be stripped and reapplied at least once every year.
Wax- based underbody coating never truly harde. During application, they drip or flow into seams and crack 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 Underbody Coating
For standard vehicles, any of the aforementioned types of underbody coating will provide sufficient protection. For large trucks and heavy machinery, asphalt-based underbody coating provides a bit of extra durability against rocks, chips and moisture.
Asphalt-based underbody coating 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 underbody coating also needs more cure time than the other three, and is not paintable, making it best to use only for undercarriages.
The Pros of Undercoating
The obvious pros undercoating are the protection it provides to the carriage of your vehicle. If you live in a place where salt and sand on the roadways in cold weather, these materials can be corrosive to your vehicle. Undercoating gives you an extra layer of protection against rust and corrosion, protecting your car. Undercoating will eventually wear out, but you can get years of protection from it. Even vehicles in warmer climates gain protection as debris is repelled and kept away from eating at the vehicle.
Cons of Undercoating
When examining the vehicle undercoating pros and cons, you do want to look at potential downsides to getting undercoating. Undercoating will work best on new vehicles that have not been exposed to road conditions. A used vehicle may already have residue on the bottom of the car or even have spots of rust and corrosion. Undercoating will not help you if corrosion already exists and the corrosion needs to be removed first before it can be applied, which can be expensive for you.
EXAMPLE
The main purpose of undercoating is to prevent stone clips, prevent paint chipping, protect against rust and corrosion ,protect vital components , reduce noise vibration and harshness.
