Why Your Truck’s Side Steps Keep Rusting (And How We Fixed It)

If you’ve owned a truck for more than a year, you’ve probably seen it: that annoying bubbling of paint or the first signs of orange rust on your side steps. Most people think it’s just part of owning a rig. We disagree.

The problem isn't the steel—it's the coating. At TRUMGETA, we decided to stop using standard finishes and moved to something much tougher: Auxchemic® (AC) Polyurea.

Here is why this tech is actually worth the hype:

It’s a "Seamless Armor" for Your Steel

Most powder coatings have tiny, microscopic holes that you can’t even see. Moisture and road salt crawl into those holes and eat your steps from the inside out.

Our AC coating is different. It’s 100% solid and solvent-free, which means it forms a single, continuous, and non-porous shield over the metal. It doesn't just "sit" on the steel; it creates a chemical bond that’s nearly impossible for water or salt to penetrate.

Hard but Not Brittle: The Impact Secret

Standard coatings are hard, but they’re also brittle—kind of like a ceramic plate. When a rock flies off your tire at 60 mph, it cracks that "plate," and the peeling starts.

Auxchemic® has an elongation rate of 300% to 1000%. We describe it as "Hard but not brittle, soft but not weak". When a stone hits the step, the coating flexes to absorb the impact and then bounces back. No cracks, no flakes, and no bare metal exposed to the elements.

Built for the Real World

We know our trucks don't stay in the garage. Whether it’s a 100°F summer in the desert or a -40°F winter in the mountains, your gear has to hold up.

This coating stays stable from -40°C all the way up to 150°C. It’s built to resist UV rays, so it won’t turn that ugly chalky-grey color over time. Plus, that aggressive texture isn't just for looks—it gives your boots a massive amount of grip in rain, mud, or snow.

The Bottom Line

You shouldn't have to replace your side steps every few seasons. Because Auxchemic® is so durable and resistant to aging, these steps are designed to last 20 to 30 years.

It’s a one-time investment to keep your truck looking sharp and your footing solid for the life of the vehicle.
