Underbody Coating

Under body coating:

• Under body protective coatings is used to protect the vehicle chassis from external environment, to ensure the integrity and safety of cars. The use of UBC plays a very important role in the service life of the vehicle. In general, it is required to spray such a protective coating in the manufacturing of the new car. Due to the highly competitiveness of new car sales, car producers have pressure to reduce the manufacturing cost, so that they reduce or even completely eliminate the use of under body coating where it is not to be easily seem by car owners. As a consequence, our car service life will be greatly reduced.
• Many car owners all know to regularly maintenance the vehicle by changing the engine oil and having the paint polished, but little attention has been paid to the bottom of the car. There are many car that the surface looks glossy, while the under body already rusting.

PURPOSE OF USING UBC:

1. Prevent from stone chip:

• There are thousands pieces of stones on the road, and they are constantly hitting your car on the under body, wheel arches, sills and the trunk lower part while driving on the road. In some cases, the under body might be scratched by uneven road. As such the thin corrosion protection coating on the metal sheet will be destroyed and leave the bare metal exposed to the air, which will soon come to corrosion when contact with the moisture in the air. If not promptly getting anti-rust treatment, then the rust will soon spread to large areas. Under body coating or the anti-stone chip coating is a thick elastic layer which could not be easily damaged by stone chipping or scratch, therefore could basically protect the metal sheet of the under body.

2. External influence:

• External environment, the baking from the hot road in summer, the road's anti-frozen gent in winter, raining water and the salty water in the atmosphere, will attach the under body of a car. Particular in coast areas, the wind from the sea will bring more salt to the air, which will accelerate the corrosion and reduce the service life of a car. While the under body is covered by the thick and tight layers, it would act as a strong barmo to prevent these external substances attaching the metal sheet.

3. Keep the value:

• A car could keep a high value while it is well maintained. It means that if a car is well treated on under body protection, it could keep the car in a good condition and extend the car's service life. or you could charge a higher price in a used-car trading.

4. Improve driving comfort:

• After curing the under body coating becomes a thick elastic coating covering the whole under body, which could act as a good dampening material, significantly reduce the vibration of the metal sheet and reduce the noise inside the car.

  

Types of Vehicle Undercoating:

• Having undercoating 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 undercoating available.

Rubberized Undercoating:

• Rubberized vehicle undercoating 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 unaxidized 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 undercoatings 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.

  

Advantages of Underboady coating:

• Undercoating gives 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.
• It can be self-applied.
• It minimizes the sound from underneath the car.
• It insulates the interior of the car from the extreme temperature from beneath the vehicle.
• The coating does not chip away when hit by stones.

Disadvantages of Underboady coating:

• Undercoating will not help you if corrosion already exists and the corrosion needs to be removed first before it can be applied, which canbe expensive for you.
• It must be reapplied every 3 to 5 years for the best results.
• It adds weight to the vehicle.
