What Is ArmorThane?

Do we have free will?…

Is the universe deterministic?…

What is consciousness?…

These are all great questions that some of the greatest thinkers have pondered throughout time. Another great question deliberated on by some of the brightest minds is “What is ArmorThane?

Not surprisingly, for many enthusiasts, getting to the bottom of what the ArmorThane brand of bed coating is all about—thoroughly and accurately—is the truck scene’s equivalent of conquering a very complex puzzle.

Is ArmorThane just a material? Is it a style? Is it a method? Unfortunately, the process has become generalized—a synonym of sorts—the same way that the masses say “bulletproof” to describe fortifying a Ford 6.0L, 6.4L, or 6.7L Power Stroke engine’s top half. The problem is, when they perform the procedure, they’re doing so without using BulletProof Diesel’s patented system. 

We have often heard the inaccuracies: “I’m going to get the bed Armored, or ArmorThane’d. My buddy is doing it for me in his garage.” While that friend may very well be coating the truck’s bed, if he isn’t an ArmorThane technician and using the company’s proprietary materials and equipment, it’s not the real deal. In a nutshell, the bed is being coated. Period. That’s how it should be phrased.

So, What IS ArmorThane?

Before we get into the process, let’s look at the chemical itself first. For clarity, we spoke with Hank Strathman, operations manager for ArmorThane Corporation, who provided insights about the substance. “ArmorThane is a coating system based on a proprietary two-component spray elastomer,” says Hank.

It’s neither paint, plastic, nor rubber. The A and B properties are:

  • Isocyanate.
  • A hardener.
  • Resin (that comprises 12 different components)/polyurea in barrels.

“Unlike other bed lining products, there are NO volatile organic compounds (VOCs) in the ArmorThane chemical. There are only solids, no solvents, which means the substance reacts instantly. It’s solid within four seconds after it is applied to a surface—something that cannot be replicated with canned DIY coating products. Because of this quick reaction, applying ArmorThane truly is an art,” Hank says.

How ArmorThane Is Applied

A spray gun is a device that executes an “impingement mixing” process, where Components A and B are heated to approximately 130-210 degrees Fahrenheit and collide under 2,000 psi of pressure at the tip of the gun. The strong coating that is blasted into the bed is the result of this reaction.

Rob is a master ArmorThane installer with 13 years of experience. After starting the reactor, he immediately begins spraying the bed, moving quickly with side-to-side sweeps and using his own (counting the number of passes over an area) method to gauge the consistency of the application. 

Bold, Durable Finish

Rob finishes the job with the spraying completed by removing the masking materials, reinstalling the tailgate, and validating the job through a thorough inspection and a digital thickness gauge. The ArmorThane treatment is typically 1/8 inch thick. While Black is the standard pigment for the coating, ArmorThane can blend body-color and custom colors for specific applications.


We are extremely pleased with the final product. The ArmorThane coating immediately brings “modernity” to our old rig, and, more important, it adds protection for the bed floor, sides, and rails against scratches and dents caused by payloads.
