How Much Does It Cost to Undercoat a Truck?

Undercoating a truck is essential in protecting it from rust and corrosion, insulating it from noise and vibration, and even improving gas mileage. But how much does it cost, and what are the best undercoating options? Read on to find out.


Costs of Undercoating

The cost of undercoating a truck depends on several factors, such as size and type. Generally, the cost ranges from $200 to $500. However, obtaining a quote from a reputable company and asking about any discounts or specials they may be running is essential.

Rust Proofing

Rust proofing is another crucial aspect of maintaining a vehicle’s longevity. Rust-proofing services are available at car dealerships, auto body shops, and convenience stores. The cost varies depending on the service chosen and the truck’s size. Rust Check, Krown, and Corrosion Free are some providers, with prices ranging from $120 to $170.

Undercoating Over Rust

Undercoating can still protect a truck from further corrosion even if it has already been damaged by rust. The initial undercoating process involves the following:

  • Cleaning up any accumulated rust, dirt, and gunk.
  • Ensuring that the undercoating adheres correctly to the metal surface creates a barrier against moisture.
  • Salt.
  • Other corrosive elements.

Is Undercoating Worth It?

Undercoating is an extra layer of paint or sealant applied to a car’s underside, protecting the metal from corrosion, rust, and damage caused by the elements. While modern vehicles come with a warranty that covers corrosion damage and car manufacturers provide good corrosion protection, undercoating may be worth it for those planning to keep their trucks for an extended period or living in areas with severe weather conditions.

Best Undercoating Products

Choosing an undercoat designed explicitly for trucks is crucial for optimal results. Rust-Oleum Professional Grade Undercoating Spray is recommended for easy application and excellent protection against rust and corrosion. Fluid Film Undercoating is a superior product, while 3M Professional Grade Rubberized Undercoating is a budget-friendly option.

Ziebart Undercoating Services

Ziebart offers a variety of undercoating packages for different levels of protection. The cost of the services varies depending on the vehicle type and the desired protection level. Ziebart’s popular Gold Package includes an undercoating and a rust-inhibiting spray. In contrast, the Platinum Package includes a paint sealant for an additional fee.

DIY Undercoating

While it is possible to undercoat a truck, it requires the right equipment, space, and patience. A handheld undercoating gun and compressor are needed, and enough room for a messy job should be available. Rushing the job will result in an inadequate finished product.


Undercoating a truck is crucial for long-term maintenance, protecting against rust and corrosion, and improving insulation and fuel economy. The cost of undercoating services depends on various factors, but obtaining a quote from a reputable company is essential. Choosing the best undercoating product for a truck’s needs is crucial for optimal results.
