Corrosion and Rust Prevention Tips

Your work truck is built to withstand the day-to-day rigors of the jobsite. But one of the most crucial challenges your truck faces is withstanding mother nature. Through our industry-leading,  12-step E-Coat Primer system for our steel bodies, we are confident that both Knapheide steel and aluminum bodies are the industry standard in corrosion resistance. But, that doesn’t mean you shouldn’t always take every necessary precaution for you entire work truck.


One of the first steps in preventing rust and corrosion is understanding how it’s formed. Rust and corrosion are the result of moisture making its way under openings in your paint. These openings are created by rocks and debris that are thrown at the body of the vehicle while driving.

In its infancy, rust appears as raised paint bubbles on the body or frame of the vehicle. Though they may be difficult to detect initially, by using a flashlight or parking in a well-lit area, they can be more easily seen. Earlier detection will allow you to more quickly remedy the issue through touch-up.

Now that we understand how rust is formed, here are some of the preventative measures you can take to prevent this from happening to your work vehicle.


Just as you would with your daily driver, it’s important to keep your work truck clean. This is especially important for those who work in areas near salt water or those that use salt to treat roads during winter weather. As salt can accelerate the rust and corrosion process, regularly washing your truck to rid it of the salt will aid in prevention.


If available, always leave your vehicle parked in an enclosed, climate-controlled environment such as a garage or shed. Parking in an enclosed space offers your truck protection from elements such as extreme temperatures, wind, rain, and overexposure to sunlight, all elements that can have a negative impact on your vehicle.

These elements can weaken the protective finish coat of your paint, exposing your truck to a greater risk of developing rust and corrosion.


Many companies now utilize materials and processes that are optimized to prevent rust and corrosion. One such process is undercoating the body of the vehicle. This process involves coating the undercarriage with a sealant to protect the frame from the typical causes of rust and corrosion.

These sealants come in a variety of forms including rubberized, polyurethane, wax, asphalt, and many other bases. Each has its own unique set of benefits that assist in prevention.

Most manufacturers now utilize a factory process of undercoating or rust prevention. Additionally, the process can be performed by an aftermarket business. In some cases, though a lot of work is involved, the process can be done at home.

Rust and corrosion prevention are a key component in keeping your work vehicle in prime condition. Taking these precautionary measures will assure that your truck has longevity, allowing you to continue working confidently for years to come.
