Bedliner on a Jeep: Full-Body, Tub and Rocker Coatings Explained

A Jeep takes abuse in places a pickup never sees. Rocks hit the rockers, branches drag down the sides, mud and sand get packed into the tub, and the floor gets wet every time the top comes off. A sprayed polyurea liner handles all of that, which is why you see it on everything from rocker panels to entire bodies.

The coating is the easy part. Polyurea gels within seconds of leaving the gun, so a skilled applicator can cover a Jeep quickly. The real work, and most of the price, is in what gets taken apart, masked and prepped before anyone pulls the trigger.

Three ways to coat a Jeep

Rockers, fenders and bumpers

This is where most owners start. The rocker panels and lower doors take the hits on the trail, and steel bumpers and sliders get scraped constantly. A textured liner on these areas soaks up rock chips and is easy to touch up. Plastic fender flares can be coated too, but plastic needs its own prep and an adhesion promoter, so ask the shop how they handle it.

Tub and interior

Coating the inside of the tub means pulling the seats, carpet, console and trim, then spraying the floor, wheel tubs and cargo area. You end up with a floor you can sweep or rinse, and a bit less road noise. If you plan to hose it out, first look at where wiring, connectors and any modules sit near the floor, and make sure the drain plugs stay usable.

Full body

A full-body job covers every exterior panel, sometimes along with the tub and the underside of the hood. It gives you the toughest finish you can put on a Jeep, and it takes the most labor. Many shops build the rockers and lower panels heavier and keep the upper panels lighter so the texture looks even and the weight stays down.

Disassembly and masking: where the hours go

A clean full-body job starts with taking things off. Doors usually come off their hinges so the jambs and edges can be sprayed or masked cleanly. Lights, mirrors, the grille, badges, fender flares, door handles and often the hood come off as well.

Whatever stays on gets masked. That includes the glass, the windshield frame and its seal, door seals, hinge pins, latches and strikers, the fuel door, wiring harnesses and any sensors or cameras. Edges are where a liner job looks professional or looks amateur, so ask how the shop finishes tape lines at seams and openings.

Then comes prep. Paint gets scuffed or abraded so the liner has something to grip, and every surface is degreased. Bare metal gets primed where needed. Any rust has to be dealt with at this stage. Polyurea is not a structural repair, so rot and rust-through must be cut out and patched before anything is sprayed, or the rust keeps spreading underneath.

Texture, color and the UV topcoat

Texture is adjustable. A heavier texture gives more grip on rocker steps and the tub floor, and it hides small dents and waves in the body. A finer texture looks cleaner on upper panels and is easier to wash. Ask to see sample panels sprayed at the texture you are getting.

Color is where many Jeep owners get surprised. Most standard liners are aromatic, which means they chalk and fade with sun exposure, and black slowly turns grayish. An aliphatic topcoat over the liner holds color and sheen far better. On a vehicle that lives outside with the top off, that topcoat matters more than it does inside a truck bed. Tinted and color-matched liners are available, and they cost more.

What a Jeep liner job costs

Every shop prices this differently, and region, prep and how much comes apart change the number a lot. The ranges below are rough starting points for a Wrangler-sized vehicle, not quotes.

Things that push a quote up include full door and hood removal, rust repair, color or color matching, a UV topcoat, extra thickness on the lower panels, and coating the underside of the hood or the door interiors. Bolt-on parts you remove and drop off yourself can bring it down at some shops.

Trail rash and repairs

This is where a liner earns its keep. A scrape that would go through paint usually just scuffs the textured surface. Deeper gouges can be cleaned, scuffed and re-sprayed, and the patch blends in well because of the texture. A faded area can be topcoated again.

A dent is another story. The liner moves with the panel, so a hard hit often leaves the coating intact over bent metal. To fix the panel properly, a body shop has to cut back the liner, repair and refinish the metal, then have the liner patched. Keep that in mind when you pick your lines on the trail.

For upkeep, wash it like any other finish and avoid harsh solvents. Our bedliner maintenance guide covers cleaning and touch-ups in more detail.

Resale: plan on it being permanent

A bonded liner does not come off easily. Removal means grinding, chemical stripping or blasting, and the panels usually need bodywork and paint afterward. If the Jeep is leased, or you may want the factory paint back someday, coat only the removable parts.

Resale cuts both ways. Off-road buyers often see a liner as a plus, while others wonder what is under it. Take dated photos of the bare body during prep and keep the shop invoice. That record answers the obvious question when you sell.

How to vet a shop

Ask to see a Jeep or another full vehicle they have coated, in person if possible. Look closely at the edges around the door openings and lights. Then ask direct questions:

• What comes off the vehicle, and what gets masked?
• How do you prep painted panels, bare metal and plastic?
• What thickness are you building on the floor and the rockers?
• Is the liner aromatic, and is an aliphatic UV topcoat included?
• What happens if you find rust during prep?
• What does your written warranty cover?

If you are weighing different chemistries, our explainer on polyurea vs polyurethane lays out the differences. A good shop will answer every one of these questions plainly and put the scope in writing before you drop the Jeep off. Own a side-by-side too?
