The 10 Best Truck Undercoatings
We spent 28 hours on research, videography, and editing, to review the top options for this wiki. Maintaining a truck isn't easy, and many don’t realize that the undercarriage is particularly vulnerable to damage from dirt, moisture, and chemicals. Here you’ll find a variety of undercoatings that will create a strong barrier to keep your investment running smoothly. Remember to take the proper safety measures and use protective equipment - like goggles, gloves, and masks - when applying these.

There are different varieties of undercoating options, including those with wax, oil, or asphalt bases. All of these have been incorporated into our list to suit varying consumer tastes and needs. We prioritized strong rubberized coatings since they offer easy application and are reliably durable, but we included alternatives as well, such as POR-15 45404 (which goes on in thin coats like paint) and Fluid Film Prevention, a more eco-friendly option. While all of the selections on our list can be used to protect any automotive vehicle and even boats and RVs, our highest ranking items are especially well suited to trucks, particularly our #1 choice, Dynatron 544 Dyna-Pro, which was engineered by 3M to be exceptionally heavy duty. For those who don't have the option of a spray gun or don't want to deal with a brush, we included multiple choices that come in aerosol cans for convenience. We also added Chemical Guys Bare Bones for users who need adequate protection, but also value the aesthetic of a glossy appearance.
We cannot stress enough to follow proper safety protocols when applying any of the selections on this list - follow the directions on the label and ensure that your solutions are stored in the proper manner, away from heat. Protect yourself with a mask, goggles, and clothing to avoid breathing vapors in or allowing your eyes and bare skin to come into contact with these substances. It's also a good idea to lay down a tarp before beginning, to ensure your floors remain clean, and to carry out your application in a well-ventilated area.
