1. Raptor Liner Spray On Bedliner Kit: Top Pick
In our research, the Raptor Liner kit consistently earns high marks for its tough, UV-resistant finish. Owner feedback highlights its ability to withstand heavy loads and weather without peeling. The included spray gun simplifies application, though achieving a uniform texture takes practice. We found it suitable for both DIY enthusiasts and professionals seeking a reliable, long-lasting bedliner.
However, the kit’s coverage is limited to one coat on a standard short bed; a second coat may require an additional purchase. Users with large trucks or those wanting a thicker build should budget for extra product. It is not ideal for those seeking a quick, no-prep solution, as surface prep is critical for adhesion.
- Excellent adhesion and chip resistance based on owner feedback
- UV stable formulation resists fading and cracking
- Complete kit with gun, hose, and hardener for easy application
Pros: Outstanding durability for heavy use; Smooth spraying with minimal drips
Cons: Requires careful surface prep for best results
2. UPOL Raptor Tintable Bedliner Kit: Runner Up
The UPOL Raptor Tintable kit stands out because it can be tinted to match your truck’s paint. Based on manufacturer data and owner reports, the cured liner offers excellent resistance to chemicals and impacts. The application process is straightforward, but adding tint requires careful mixing. We found this best for owners who want a factory-matched look without sacrificing protection.
That said, the need to purchase tint separately and the risk of inconsistent color if not mixed properly are drawbacks. Users who simply want a black liner may find better value in non-tintable options. It is not recommended for those on a tight budget or with no spray painting experience.
- Can be tinted with automotive paint for color matching
- Strong chemical and impact resistance per spec sheet
- Complete kit with spray gun and instructions
Pros: Color customization is a unique advantage; Durable and easy to clean
Cons: Tinting adds extra cost and complexity
3. Herculiner Truck Bed Liner Kit: Budget Friendly
Herculiner is a popular budget option that applies with a roller, making it accessible to anyone. Owner feedback indicates it holds up well for daily driving and light hauling. The UV resistance is a plus for trucks exposed to sun. However, the texture is rougher than spray-on liners and may chip under heavy abuse. We see it as a good entry-level choice for protecting a bed on a tight budget.
But for those who frequently carry heavy, abrasive loads or want a professional finish, this kit falls short. The application can be messy, and achieving a uniform thickness is difficult. It is not suitable for commercial use or owners who demand maximum durability.
- Affordable roll-on application no spray equipment needed
- Provides good protection for light to medium use
- UV resistant formula reduces fading
Pros: Very low cost compared to spray kits; Easy to apply with included roller
Cons: Roll-on finish can be uneven and less durable than spray
4. Dupli-Color Bed Armor Spray On Bedliner Kit: Best Value
Dupli-Color’s Bed Armor offers a balance of affordability and performance. The 5-liter kit covers a full-size bed with one coat, and the aerosol cans simplify application. Owner reviews praise its adhesion and resistance to minor impacts. We found it a solid choice for weekend warriors who want decent protection without investing in a spray gun.
However, the single-component formula is less resistant to chemicals and heavy abrasion than two-part polyurethane kits. Users who frequently haul gravel or construction materials may see wear over time. It is best for light-duty use and owners who prioritize convenience over maximum toughness.
- Large 5-liter coverage for full-size beds
- Aerosol cans are easy to use without a compressor
- Includes cleaning wipes and sandpaper for prep
Pros: Generous coverage for the price; Convenient aerosol application
Cons: Not as durable as two-component spray kits
5. Grizzly Grip Spray On Bedliner Kit: Heavy Duty
Grizzly Grip is designed for severe use, with a high solids formula that builds a thick, protective layer. Based on owner feedback from tradespeople, it stands up to heavy cargo and harsh weather. The flexibility helps prevent cracking in temperature extremes. We recommend this for commercial trucks and off-road vehicles that need maximum protection.
On the downside, the kit does not include a spray gun, so users need to purchase or rent one. The thick consistency can be challenging to spray evenly for beginners. It is overkill for light-duty use and not the best choice for DIYers on a budget.
- High solids content for thick, durable coating
- Excellent impact and abrasion resistance per manufacturer
- UV stable and flexible to prevent cracking
Pros: Extremely tough finish for heavy loads; Good flexibility reduces chipping
Cons: Higher price point and requires spray equipment
6. Monstaliner Do-It-Yourself Roll-On Bedliner Kit: Best Roll On
Monstaliner is a roll-on alternative that offers decent durability for the price. Owner reports indicate it holds up well to sunlight and light cargo. The ability to tint is a bonus. However, the application is labor-intensive and the final texture is coarser than spray-on liners. We see it as a viable option for those who cannot use spray equipment and want a UV-resistant coating.
But for heavy use, the roll-on finish is more prone to peeling if not applied perfectly. It also takes longer to cure than spray-on products. Not recommended for those seeking a smooth, professional look or maximum abrasion resistance.
- Roll-on application with no special tools
- UV stable and resistant to fading
- Can be tinted with optional color packets
Pros: Good UV resistance for sunny climates; Easy touch-up if damaged
Cons: Roll-on texture is rough and can be uneven
7. SEM Rust Shield Bedliner Aerosol Kit: Corrosion Protection
SEM Rust Shield is formulated with corrosion inhibitors, making it a good choice for trucks in salt-belt regions. Owner feedback notes it works well for touch-ups and small bed areas. The aerosol application is simple, but the coating is thinner than traditional bedliners. We found it best for protecting against rust rather than heavy wear.
However, it is not designed for full bed coverage under heavy loads. The thin film can be scratched through with abrasive cargo. Users expecting commercial-grade durability will be disappointed. It is ideal for those prioritizing rust prevention over impact resistance.
- Contains rust inhibitors for added protection
- Aerosol cans for easy spot repairs
- Textured finish hides imperfections
Pros: Rust inhibiting properties are unique; Convenient for small areas and touch-ups
Cons: Not as durable as full bedliner kits
Frequently Asked Questions
Do I need to sand my truck bed before applying a spray in bedliner?
Yes, most manufacturers recommend scuffing the surface with sandpaper (80-120 grit) to promote adhesion. Some kits include prep materials. Skipping this step can lead to peeling.
How long does a spray in bedliner take to cure?
Cure times vary by product. Most two-component polyurethane kits are dry to the touch in 1-2 hours and fully cure in 24-48 hours. Roll-on liners may take longer. Always follow the manufacturer’s instructions.
Can I apply a spray in bedliner over an existing drop-in liner?
It is not recommended. Drop-in liners can trap moisture and cause rust. For best results, remove the old liner, clean and prep the bare metal, then apply the spray in bedliner.
Will a spray in bedliner prevent rust?
Yes, when applied correctly over clean, bare metal, a spray in bedliner seals the surface from moisture and oxygen, preventing rust. Some kits also include rust inhibitors for extra protection.
How much coverage does a typical kit provide?
Coverage depends on the product and thickness. A 4-liter kit usually covers a standard 5.5-foot short bed with one coat. For full-size trucks or thicker coats, you may need two kits. Check the manufacturer’s coverage estimates.
