Underbody Coating

UNDERBODY COATING

Underbody coating provides long term protection from corrosion to car's underbody. It also protects parts like internal body panels, frame rails & other inner cavities that are not physically accessible but are prone to corrosion.

  • Car body is made up of several metals such as Iron, Steel, Aluminium, Copper etc. Rusting is the common term for corrosion of iron & its alloys.
  • It is a must to make sure the underbody is given a layer of protection from all grime & grit & annual clean up & touch up is necessary.
  • Corrosion is the reaction of iron & oxygen, as may present in water or air moisture.
  • Because it is not in plain sight, we often do not see the damage. Underbody coating or treatment offers a long term solution for issues related to corrosion & rust.
  • The underbody of the car is exposed to most wear & tear caused by dirt grimes, bad roads, stones & muddy water. Since it is not visible in plain sight, we often do not see the damage. This treatment makes a corrosion resistant protection film on the underbody surface that protects it from rust & abrasives & covers under chasis & wheel arches.

ELECTRO COATING

E-coating is an immersion wet paint finishing process that uses electrical current to attract the paint product to a metal surface. This process is also referred to as paint deposition.

TYPES OF UNDERBODY COATING

RUBBERIZED UNDERCOATING

Rubberized vehicle undercoating is easy to apply & offers sound-cushioning as well as protection from dust, moisture & dings or dents. In addition to your undercarriage, rubberized undercoating is also safe to use on wheel wells & quarter panels, & dries to a soft rubbery finish that prevents further rust, damage or moisture seeps. The coating can be painted over & 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 & best protective measures against rust & 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 & 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 & seams, displacing salt & moisture & oozing around rusty areas to bond with & protect unoxidized metal. It also sands quickly in case you will need to perform bodywork & can be painted over. On the flipside, this type of car undercoating generally requires a little bit more surface prep work before applying--sanding & applying an etching primer to bare metals before using are generally recommended.

WAX OR PARAFFIN-BASED UNDERCOATINGS

A paraffin-based undercoating will be the cheapest & 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 & will need to be stripped & reapplied at least once every year. Wax-based undercoatings never truly harden. During application, they drip or flow into seams & cracks to provide protective properties. They are usually available in a spray gun canister or in an aerosol can & 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 & heavy machinery, asphalt-based undercoating provides a bit of extra durability against rocks, chips & moisture. Asphalt-based undercoating generally contains a little bit of rubberized material that sets up firmly and also helps soften noise.

ADVANTAGES

  1. Undercoating gives an extra layer of protection against rust & corrosion, protecting your car.
  2. 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 & kept away from eating at the vehicle.
  3. It can be self-applied.
  4. It minimizes the sound from underneath the car.
  5. The coating does not chip away when hit by stones.

DISADVANTAGES

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