Undercarriage Protection

Vehicle undercoating is a process where a protective layer is applied to the underbody of a car. The layer acts as a barrier between the metal parts of the car and the elements that can cause rust and corrosion. We also offer rust proofing service to protect your vehicle from rusting inside out and premium rust treatment with rust inhibitor to prepare older vehicles for undercoating. It doesn't matter if it is car, van, truck or RV - we've sprayed all of them!

What exactly is rust and why is it so bad?

Rust is the chemical process of oxygen and water combining with iron (like the steel in your car, truck, van or SUV). When those elements find unprotected steel, they merge forming the brown, flakey material we call rust. Rust corrosion will eventually eat completely through your metal vehicle unless you stop rust.

Why is vehicle undercoating important?

The underbody of a car is one of the most vulnerable parts to rust and corrosion, as it is constantly exposed to moisture, salt, and other elements that can cause damage. Over time, rust can weaken the metal parts of the car and lead to structural damage. Vehicle undercoating helps to prevent this by creating a barrier that protects the metal parts from the elements.

What are the different types of undercoating?

There are three types of vehicle undercoating: wax-based, rubberized, and oil-based.

Wax-Based Undercoatings:
Wax-based undercoatings, such as Fluid Film and Surface Shield, are thicker and more viscous, providing excellent protection against moisture and salt. However, they need to be reapplied periodically. A notable option in this category is PSC Black Wax. Unlike Fluid Film and Surface Shield, PSC Black Wax is not as thin and is semi-drying. This characteristic allows it to stay on longer, offering extended protection without the need for frequent reapplication.

Rubberized Undercoatings:
Rubberized undercoating is thinner and more flexible, making it better for providing a sound-deadening effect, which is ideal for new vehicles. The product we use, Tectyl 2102, has proven to be a fantastic option when rust hasn't yet formed. However, you must be careful when applying rubberized spray because it can trap moisture if not applied correctly. This trapped moisture can lead to rusting, defeating the purpose of the undercoat.

Oil-Based Undercoatings:
Oil-based undercoatings, like NHOU, offer a unique solution by seeping into seams and crevices, displacing moisture, and preventing rust from forming. It is important to note that NHOU is not applied in our shop unless the customer provides their own material. This ensures that the oil-based undercoat meets the specific preferences and requirements of the customer.

BENEFITS OF rust proofing:

Our rust proofing service gives you the best corrosion protection available. Seals the metal and blocks oxygen, water, salt and other chemicals from touching the metal surfaces.Seals vehicle body cavities where rust likes to start. This will not affect the appearance of your vehicle!

How is vehicle undercoating applied?

Vehicle undercoating is applied by spraying the underbody of the vehicle with the protective coating. The underbody of the vehicle is thoroughly cleaned to remove any dirt, grime, and rust before the coating is applied. The coating is then allowed to dry completely before the vehicle is moved.
