1. Best Overall Spray In Bedliner: U-Pol UP0820

U-Pol Raptor Black Urethane Spray In Bedliner

  • Color: Black
  • Quantity: 1 gallon

U-Pol's Raptor is the best overall spray-in bed liner on our list because it is easy to use, dries quickly, and offers all-round protection.

The kit includes 3 liters of a black bed liner base in 750 ml bottles and a liter of hardener. These are easy to use because they should be mixed in the ratio of 3:1, then sprayed. That said, a free application gun is included for this job.

Once applied, the bed liner dries very quickly to form a hard UV-resistant coat that does not fade. In addition to this, it makes the truck bed water, stain & scratch resistant, and helps to dampen sound & vibrations when carrying loose items.

Although the included spray gun might need a special adapter to work with some air compressor types and models, this should not be a deal-breaker. These adapters are cheap and easy to get in your local hardware store. Also, the 4-liter quantity (about a gallon) might not be enough for large trucks.

Pros:

  • Easy to use
  • Free spray gun
  • UV, water, stain & scratch resistant
  • Dampens sound and vibrations
  • Fast drying formulation

Cons:

  • No gun adapter
  • Might not be enough for large trucks

2. Best Professional Spray In Bedliner: Custom Coat 5864267669

  • Color: Black
  • Quantity: 1 gallon

Apart from having a high-quality formulation, you need the right tools for professional bed-liner application. Custom Coat's 5864267669 gives you this in the form of a spray gun with a regulator. This enables you to check and control the air pressure in the gun for perfect adhesion.

That said, the kit includes four 24-oz. cans of the black liner base, four 8-oz. cans of the hardener, and a technical data sheet & user manual to explain how to mix and apply the solution. Overall, you get a gallon of bed liner that can cover up to 130 square feet.

Besides using the spray gun, it is also possible to apply this bed liner using a brush or roller if you prefer a different texture.

Once applied, the coat protects from rust, corrosion, and scratches. It also adheres to the surface firmly for maximum durability, forming a soft layer that deadens sounds and vibrations. While doing so, it remains waterproof, heat, and UV resistant.

On the downside, the product forms a thin layer if sprayed to cover 130 square feet. As such, it might not be highly protective as compared to a thick coat.

Pros:

  • Spray gun with a regulator
  • Wide coverage (up to 130 sq. ft.)
  • Excellent adhesion
  • Dampens sound and vibrations
  • Waterproof, heat and UV resistant

Cons:

  • Forms a thin coat

3. Best Spray In Bedliner for the Money: Linerxtreeme AA1 

Linerxtreeme Spray In Bedliner With Gun

  • Color: Black
  • Quantity: 3 gallons

Linerxtreeme's AA1 is designed to give you a beautiful, long-lasting semi-gloss finish on your truck bed that is worth the money.

With only a few coats of this bed liner, you get a hard and tough surface that provides maximum protection from UV damage, scratches, stains, and corrosion. 

You also get enough quantity (3 gallons) to cover two short bed trucks or one 8-foot truck bed. In actual numbers, it can cover up to 100 square feet.

Application is relatively quick and easy as the manufacturer provides a free spray gun, plus precise & easy-to-follow instructions.

As for quality, you can bank on the brand's 20 years in business, as well as thousands of repeat customers. The only downside is that the product lacks a regulator to check the air pressure when spraying.

Pros:

  • Long lasting semi-gloss finish
  • Protects against UV damage.
  • Wide coverage (up to 100 sq. ft.)
  • Comes with a free spray gun
  • Scratch, stain & corrosion resistant

Cons:

  • No regulator

4. Universally-Compliant Spray In Bedliner: Speedokote SMR-1000-K4

Speedokote T-Rex SMR-1000-K4 Spray In Bedliner

  • Color: Black
  • Quantity: 1.7 gallons

Speedokote's SMR-1000-K4 is the only 50-state compliant spray-in bed liner because it is within the safe emission zone of 1.7 lbs. of VOC/gallon. Despite this, it still is a true 2K urethane that offers excellent adhesion to steel and sanded paint.

That said, the product withstands the same atmospheric conditions as a high-quality, single-stage urethane topcoat, and dries quickly to form a UV & chemical resistant finish. The coat is also waterproof and flexible, which helps in dampening sound and vibrations.

Applying the bed liner is easy as the manufacturer provides a free spray gun and detailed instructions. And all you need to do is add in the hardener, shake the mixture, then spray it on a clean truck bed.

However, the product does not provide enough anti-skid properties, which is important for transporting loose, slippery goods.

Pros:

  • Safe and compliant in all 50 states
  • Excellent adhesion
  • UV and chemical resistant
  • Dampens sound and vibrations
  • Easy to use

Cons:

  • Not enough anti-skid properties

5. High-Solids Spray In Bedliner: Al's Liner ALS-BL 

Al's Liner ALS-BL Premium Spray In Bedliner Kit

  • Color: Black
  • Quantity: 1 gallon

With its 3-part blended formulation, the ALS-BL contains a high concentration of solids that give a tough and durable coat at any thickness. As such, you can use this 1-gallon pack to cover a full truck bed of any size.

Once applied, the formula creates a non-fading, UV-stable black coat that protects the truck bed from rust. It also protects against corrosion by resisting chemicals, gasoline, oil, and solvents.

That said, you can use the solution to coat other materials like wood and fiberglass, which expands your application areas.

A free sprayer, adhesion promoter, and mix paddle are inclusive, but you don't get a measuring cup. This makes it a bit difficult to prepare smaller solution quantities from the three liquid components.

Pros:

  • 3-part high-solid formulation
  • Forms a tough coat at any thickness
  • Non-fading and UV-stable
  • Rust and corrosion resistant
  • Multiple accessories

Cons:

  • No measuring cup

6. Tintable Spray In Bed Liner: U-Pol 821

  • Color: Tintable
  • Quantity: 1 gallon

If you are looking for a tintable spray-in bed liner, this is the best option. With this, you have the flexibility to change your truck bed to any color and you can apply it on original paint finishes or any self-etching primer surface.

The bed liner cures relatively fast, becoming dry enough to touch in just an hour. Therefore, you won't have to wait for long before applying the second coat.

With its high-quality formulation, you can be confident of getting maximum stain and abrasion resistance. This is in addition to protection from rust, corrosion, UV damage, and the effects of extreme temperatures.

Sound and vibration dampening are also assured, provided you mix and apply the formula correctly, which is in the ratio of 3:1 (liner base: hardener). A spray gun is inclusive, but you don't get a regulator or measuring cup.

Pros:

  • Tintable formula
  • Fast curing
  • Stain and abrasion resistant
  • Dampens sound and vibration
  • Free spray gun

Cons:

  • No regulator
  • No measuring cup

7. Fast-Drying Spray In Bedliner: PlastiKote 264

  • Color: Black
  • Quantity: 0.12 gallons

PlastiKote's 264 is a unique water-based formula that dries very quickly as compared to urethane formulas. It can still be used on the same application, though, which is spraying over OEM factory-painted truck beds.

Once dried, the formula forms a tough non-skid coat that won't crack or warp. This surface is also flexible to contract or expand with changing temperatures, resists fading, and prevents rust & scratches.

The product is easy to apply because it comes ready in a spray bottle. No mixing or measuring is required. However, it comes in a small 15-oz can, which is not enough to cover a whole truck. There is a larger pack of six that you can get to cover the entire truck bed.

Pros:

  • Quick-drying water-based formula
  • Forms a tough, non-skid coat
  • Fade resistant
  • Prevents rust and scratches
  • Easy to apply

Cons:

  • Very small quantity

8. Durable Spray In Bedliner: USC 18002

  • Color: Black
  • Quantity: 0.94 gallons

With its epoxy/Kevlar formulation, the USC 18002 is more durable compared to urethane-based solutions. It has better bare-metal adhesion and chemical resistance.

On top of this, the formula lacks isocyanate, which makes it more forgiving towards varying shop conditions. As such, you can apply the coat under a wider temperature and humidity level range as compared to urethane liners.

The kit consists of epoxy resin and activator compounds, which are mixed in a 1:1 ratio. These should be applied at a lower pressure to reduce wastage in the form of overspray.

That said, the product achieves a uniform texture and appearance easily, and an applicator gun is inclusive for the application process. The only issue is that the product is quite expensive.

Pros:

  • Durable epoxy/Kevlar formulation
  • More forgiving to shop conditions
  • Can be applied using low pressure
  • Easy to achieve uniform texture
  • Includes an applicator gun

Cons:

  • Expensive

How to Buy the Best Spray In Bedliners

How to Buy the Best Spray in Bedliners

1. Type

Aliphatic

Most aliphatic types of bed liners are polyurethane-based. They are made from materials that have better pigments, which should explain their relatively longer-lasting protection.

Aromatic

These are more affordable than aliphatic bed liners, but they fade relatively fast. Therefore, if you pick them, you should be ready to re-apply a new coat once in a while to restore the new look.

2. Bedliner Color

Before you decide on the spray-in bed liner to buy, you should consider its color and make sure it is appropriate for your truck.

Black is the most common spray-in bed liner color, and many people will prefer it because darker colors hide dirt and debris better than lighter ones.

However, a tintable color is also great for those who do not want to stick with black truck beds. This gives you more flexibility, and we recommend U-Pol's 821.

3. Ease of Use

Applying bed liner on your truck makes a good weekend DIY project. With that in mind, you do not want a product that takes a lot of time or effort to prepare.

Most important, though, make sure the liner comes with all the tools you need for easy use. These include a spray gun, measuring cups, etc.

4. Quantity

It is very inconvenient to run out of the application formula midway through your truck bed. Therefore, you should pick the right quantity, and for this, check the product's coverage, which is given in square feet.

That said, you should also avoid buying too much because  the remaining formula will probably not be effective by the time you want to renew the coat.

5. Durability

For these products, durability means no fading and resistance to the elements, scratched, stains, etc. Also, a long-lasting spray-in bed liner is one that can resist peeling and cracking. For instance, USC's 18002 has better bare-metal adhesion and chemical resistance, which makes it better at resisting peeling and cracking.

6. What is In the Box?

What you get in the box matters because it determines the value you get for your money. Apart from the liner base and hardener, look for application rollers, brushes, spray guns, measuring cups, mixing paddles, and more. The best product should come with everything you need for the application process.

7. Environment-Friendly

Most of these bed liners are made from the same materials, but some brands pay more attention to their formulations to reduce pollution. VOCs are the most common pollutants, and these should be kept as low as possible.

With that in mind, Speedokote's SMR-1000-K4 is the most environmentally-friendly product and is compliant in all of the 50 US states.

8. UV Protection

The truck bed is exposed to the sun most of the time, and thus, you should ensure the bed liner you buy is UV stable. This will make it more durable and resist fading.

Conclusion

As we wrap it up, we recommend U-Pol's Raptor as the best of the best due to its ease of use, quick-drying and all-round protection properties. The product forms a hard UV-stable coat that is water, stain, and scratch-resistant.

You can also check out Custom Coat's 5864267669 if you want a spray-in bed liner for professional use. It comes with a regulated spray gun and can cover up to 130 square feet.

For maximum durability though, you should consider the USC 18002. Though expensive, the product has better bare-metal adhesion and chemical resistance as compared to urethane-based compounds.
