Spray-on polyurea for overland builds
Armor for the road less traveled.
Seamless polyurea protection for overland trucks, 4x4s and trailers. It takes rock rash, brush, mud and road salt in stride, and it’s sprayed by certified ArmorThane applicators.

Where it goes
Every surface that takes a beating.
Tap a hotspot to see how polyurea protects it, or switch to the trailer. Anything you can unbolt — or roll into a bay — can be coated.
-
The first thing to meet a stump during a recovery. Polyurea flexes with rock strikes and cable wear instead of chipping down to bare steel.
-
Skid plates exist to get hit. A thick, elastic layer absorbs the scrape, quiets the drum of gravel and keeps rust from starting at every gouge.
-
Tires sandblast the wheel wells all day. A sprayed lining seals the seams, stops the chips and noticeably deadens road noise.
-
Sliders carry the weight of the rig on rock. Coated sliders scrape and slide without turning orange after the first trip.
-
UV, ladder scuffs and tent hardware chew up rack finishes. Coat the platform once and stop touching up powder coat every season.
-
Drawer systems, fuel cans and recovery gear grind on the bed floor. A spray-in liner seals every seam and grips cargo so it stays put.
-
Rocks thrown off the tow rig's tires hit the tongue first. Polyurea takes the chips so the frame doesn't rust from the front back.
-
Jerry cans, propane and tools rattle around in here. A lined box is waterproof, quiet and easy to hose out at the end of a trip.
-
Brush pinstriping and trail rash land on the tub sides. A seamless coat seals rivets and panel joints against water and dust.
-
Fenders take a direct hit from every rock the tire throws. A textured polyurea layer won't crack the way paint or gelcoat does.
-
Tent hardware, UV and ladder feet wear through rack finishes fast. Polyurea keeps the platform sealed and grippy.
-
Creek crossings, mud and road salt attack what you never see. Underbody coating keeps water out of welds, and potable-rated linings exist for onboard tanks.
Anatomy of the armor
Four layers. One seamless shell.
Paint and powder coat are a few thousandths of an inch of hard film. A polyurea system is built far thicker and stays elastic, so impacts get absorbed instead of cracking through to metal.

Straight answers.

Ask a questionWhat is polyurea, and why use it on an overland vehicle?
Polyurea is a two-part elastomer sprayed hot through a plural-component rig. It sets in seconds into a seamless, rubber-tough membrane that flexes on impact instead of chipping. On an overland build that means bumpers, sliders, skid plates and trailer tubs that shrug off rock rash, brush and creek crossings without the chip-and-rust cycle paint and powder coat fall into.
How long does my rig need to be in the shop?
Most of the time is prep: removing hardware, cleaning, sanding or blasting and masking. The coating itself gels in seconds and is typically ready for light handling within hours. A set of parts or a bed is often a one- to two-day job; a full trailer or full-exterior job takes longer. Your applicator will give you an exact schedule.
Can it be color matched or kept from fading?
Yes. Polyurea can be pigmented, and an aliphatic topcoat goes over it to lock in color and block UV so black stays black instead of going chalky. Textured black, coyote tan, OD green and gunmetal are popular on overland builds, and custom color matching is available.
Does it add a lot of weight?
Far less than steel armor. Weight depends on the area coated and the film thickness, so a set of sliders or a skid plate adds very little, while a full exterior adds more. Your applicator can recommend thicker coverage where impacts happen and a lighter build elsewhere.
Can you line a water tank with it?
Only with products certified for potable water. Standard polyurea is not meant for drinking-water contact, so ask for a lining that carries NSF/ANSI 61 certification for the tank. Our water tank guide covers what to check before you fill it.
What does it cost?
It depends on the part, the square footage, the prep the surface needs and the finish. Bumpers and sliders cost far less than a full trailer or full-exterior job. Send us your rig and the areas you want covered and an applicator will quote it, free and with no obligation.
Who actually sprays my vehicle?
Quotes are handled by certified applicators in the ArmorThane network, using ArmorThane polyurea and polyurethane systems. ArmorThane has been formulating protective coatings since 1989.
I want to spray polyurea myself. Where do I start?
