Three Situations In Which Undercoating Your Car Or Truck Is An Especially Good Idea
Vehicle undercoats are made of a nonreactive rubberized material that is sprayed or brushed onto the undercarriage of your car. It protects the metal components of your undercarriage from rusting or being damaged by road debris by providing a layer of protection against moisture, dust and debris. While often offered as an option on new car purchases, it can also be applied later to cars or trucks you already own.
You can either have a car undercoat applied professionally or you can apply it yourself. Most brands of car undercoating are not difficult to apply yourself, especially the ones applied by an aerosol spray. You'll have to make sure that the underside of your car is completely free of rust before applying the undercoat – inspect the undercarriage of your car carefully and sand off any rust. The undercarriage also needs to be completely dry. You don't want to trap rust or moisture against your undercarriage when you apply the undercoat.
Applying a protective undercoat to your car or truck is an especially good idea if any of the following apply.
1. You Live in an Area That Uses Road Salt
In areas where roads frequently ice over during the winter, it's common for local governments to add road salt to the roads to make driving safer. The salt lowers the temperature at which water freezes, causing the ice to melt. Unfortunately, the minerals in the road salt used to de-ice roads will collect on your undercarriage and greatly contribute to the formation of rust. A car undercoat keeps the road salt away from the metal and protects your car from rust due to road salt during colder months.
2. You Often Drive on Dirt Roads
Driving on unpaved country roads kicks up a lot of dust and debris. If there has been a recent rain or if the day is particularly humid, the dust can carry a lot of moisture. The dust traps the moisture against the underside of your car, which can rapidly begin to rust and corrode the metal. A car undercoat prevents dust from accumulating on the underside of your car and prevents rust damage due to moisture.
Debris such as rocks in the road can strike your undercarriage at high speeds, causing damage to the components. In addition, many newer cars have undercarriages made of corrosion-resistant galvanized steel. Hard bits of debris that strike the galvanized steel can scratch and damage the thin galvanized layer, which ruins its ability to resist corrosion. This means that a corrosion-resistant undercarriage can eventually rust without a vehicle undercoat to protect it.
3. Your Car Produces Annoying Noise Due to Undercarriage Vibration
Some cars experience a lot of noise coming from the undercarriage due to vibration, especially when driving at high speeds. It's especially common in older cars when the coil springs are slightly loose and the components of your exhaust system no longer fit together snugly. A rubberized car undercoat acts as a vibration dampener for your undercarriage, reducing the noise you'll hear due to vibration while driving.
By protecting your car from rust and corrosion damage, you'll extend the lifespan of your car while making it safer to drive. Rust and corrosion will spread, and rust in your brake system or drive axle is very dangerous – both can cause sudden loss of control while driving. Apply an undercoat to your car or truck to protect your vehicle and keep you and your family safe.
