Underbody Coating

Underbody Coating

Underbody coating is usually a dense cladding (often based on rubber) applied uniformly to the undercarriage of the automobile.The main purpose of undercoating is to check rust especially in the body components like frame rails along with other exposed metal parts. Underbody coating can also reduce wear and tear.

Types of Undercoating

various kinds of automotive underbody coating:

1. Rubberized Underbody Coating
   

   This is generally thought of as the best underbody coating for your car. It preserves the underbody well, protecting it from scratches. Applying this to the undercarriage is not much of a hassle either.

2. Wax Based Underbody Coating
   

   This – more or less – ephemeral undercoating will wear away in a few months’ time. On the upside, wax-based undercoating puts up a big fight against moisture. It is also the most affordable option out there.

3. Asphalt Based Automotive Undercoating
   

   Best suited for lorries, trucks and large vehicles this provides a greater degree of protection compared to rubber-based coatings. However, asphalt-based coatings contain little amounts of rubber for sound-insulation purposes. The process of applying this coating is a bit time-consuming though.

4. Polyurethane Underbody Coating

   This coating closes up splits and fractures on the underbody of the vehicle. It offers up good protection against corrosion and also bonds with the metal. Unlike in the case of asphalt-based coating, you can paint over the polyurethane coating.

   Advantages of Undercoating:

   Now we will tell you why you should consider investing in a vehicle underbody coating.

   • Fights Rust
     

     It plays an important role in keeping corrosion at bay. Underbody coating can come in handy especially if you live near the sea, where there is too much humidity, and rusting is just one of those everyday things. You should also seriously consider undercoating if you reside in a place where it snows in winter.

   • Absorbs Noise

     Believe it or not, 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.

   • 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.

   • Prolong Car’s Life
     

     Good undercoating not only defends the underbody from corrosion but also protects the engine and transmission as well! Less rusting coupled with slower wear and tear can surely add years to the lifespan of your vehicle. There would be fewer dents, dings and scratches on the undercarriage for you to fret about.

   Vehicle Undercoating disadvantages

   And here are some cons of vehicle undercoating:

   It’s Not Effective On Cars With Corrosion

   If your vehicle already has some corrosion it isn’t as effective.

   Applying undercoat over rust means that although you’re stopping more moisture and airflow to the rusted area, the rusting process will still keep happening.

   An undercoat will slow down the corrosion rather than reverse or stop it. You should attempt to remove the rust before applying an undercoat.

   This isn’t always easy though, since rust can penetrate deeply into the metal, so encapsulating the rust and then applying an undercoat could be a waste of money.

   Doesn’t Work So Well On Old Cars

   Undercoating doesn’t work so well on old cars because the residue from under the car has to be removed before the undercoating is applied.

   If you don’t remove the debris first, the already-present debris will be sealed in.

   It’s Useless On New Cars

   Undercoating might not be wise if you tend to change cars every few years, since it takes between 3 and 5 years before rust starts to show.

   In fact it might be 10 years before your car is affected in any way at all by corrosion.

   This means if you get a new car every few years then undercoating it would be a waste of money because it simply isn’t required.

   It Can Be Expensive

   Reapply it every 3 to 5 years. This is the only way to ensure your vehicle is protected properly.

   Since it can cost $1500 to get the undercoating professionally applied, this is quite a big cost to do it regularly
