what bed liner can ypu use to paint a car

[StGrace]

No, you should not use a truck bed liner to paint a car's exterior body. While it's technically possible to spray products like Rhino Lining or LINE-X on a car, the result is a permanent, thick, textured coating that significantly diminishes the vehicle's value, appearance, and performance. It is a poor substitute for professional automotive paint and is generally only considered for dedicated off-road rigs where extreme abrasion resistance is the sole priority.

The primary issue is the textured finish. Unlike smooth automotive paint, a bed liner creates a rough, rubberized surface that is extremely difficult to clean and attracts dirt. This texture also creates drag, which can negatively impact fuel economy. Furthermore, these materials are very heavy, adding unnecessary weight to the vehicle.

From a long-term value perspective, applying a bed liner is essentially destructive. It is nearly impossible to remove without damaging the original body panels underneath. If you ever want to sell the car, this modification will drastically reduce its resale value and appeal to potential buyers. For a durable protective coating that maintains a smoother finish, professional options like wraps or clear bras (paint protection film) are far superior. They shield against chips and scratches while being removable and not devaluing the car.

Consideration	Bed Liner (e.g., LINE-X)	Professional Automotive Paint
Finish	Thick, textured, rubberized	Smooth, glossy, customizable
Durability	Extreme abrasion resistance	Good chip resistance, requires care
Weight	Heavy, adds significant mass	Lightweight
Reversibility	Essentially permanent and destructive	Can be sanded and repainted
Resale Value	Drastically reduces value	Maintains or enhances value
Cost	Moderate application cost	High-quality paint jobs are expensive
Aerodynamics	Creates drag, reduces fuel economy	Smooth surface is aerodynamically neutral

I looked into this for my old Jeep. It's a bad idea for anything you care about. The texture is like sandpaper, so it holds mud and never looks clean. It also adds a ton of weight. I'd only do it on a beat-up trail truck that you never plan on selling. For anything else, it just ruins the car. Save your money for a proper paint job or a vinyl wrap if you want protection.

Think of it this way: a bed liner is armor, and car paint is skin. You're putting armor on a sports car. It will protect it from scratches, but it completely changes the character and performance. The rough surface creates wind resistance, and the added weight affects handling. It's a functional choice for a purely utilitarian vehicle, but it's a aesthetic and financial mistake for a daily driver or a car with any sentimental value.

The appeal is durability, but the trade-offs are huge. That rugged texture is a nightmare to maintain and makes the vehicle louder on the highway due to increased road noise. More importantly, it's a one-way street. You can't just change your mind later. If you want a tough, matte look, explore matte paint finishes or matte vinyl wraps. They offer a unique appearance and some protection without permanently destroying the bodywork and resale value of your vehicle.

Beyond the looks, there are practical downsides. If you get into a fender-bender, body shops can't easily repair a section coated in bed liner; they often have to replace the entire panel, which is very costly. The coating can also trap moisture against the metal if it's not applied perfectly, leading to hidden rust bubbles underneath that you won't see until it's a major problem. It’s a solution that creates more problems than it solves for most car owners.
