Custom Coat Black 1 Gallon Urethane Spray-On Truck Bed Liner Kit

In this review of the Custom Coat Black 1 Gallon Urethane Spray-On Truck Bed Liner Kit, the bottom line is straightforward: this kit is aimed at DIYers and pros who want a durable, textured urethane coating with professional-level results using a simple mix-and-spray workflow. The package includes base, hardener and an applicator gun with regulator, and it covers roughly 110 to 130 sq ft at a 10 mil wet film thickness. For anyone looking to protect a truck bed, equipment or create a non-skid surface, the main reason to buy is the combination of weather resistance and flexibility delivered in an easy-to-apply system.

Key Features

• Complete kit: Includes four 24 fl. oz. cans of black base, four 8 fl. oz. hardener cans and a spray applicator with regulator so users have everything needed to start without extra purchases.
• Easy mix ratio: The 3 to 1 mix ratio simplifies measuring and reduces mix time, making it practical for single-day DIY projects or shop work.
• Professional textured finish: The urethane formula creates a heavy duty textured surface that resists abrasion and impact while providing a uniform appearance.
• Weather and UV resistance: Heat, UV and waterproof properties protect coated surfaces from rust and environmental degradation for outdoor applications.
• Versatile applications: Suitable for truck beds, bumpers, chassis, trailers and non-skid floors such as garage concrete or wood decking, offering broad utility beyond just beds.
• Coverage estimate: Estimated coverage of 110 to 130 sq ft at 10 mils wet film thickness gives a realistic expectation for planning material needs.

Who It's For

The kit is ideal for truck owners, fleet maintenance shops and DIY enthusiasts who want a professional-grade, textured protective coating without hiring a spray shop. It suits users who value a flexible urethane that resists chipping and helps dampen sound and vibration in a vehicle or equipment application.

Those who should look elsewhere include buyers who need a small touch-up bottle rather than a full 1 gallon kit, or customers unwilling to handle a two-part urethane system; this product requires mixing and spray equipment operation, so absolute beginners who prefer brush-on simplicity may prefer roller kits instead.

Pros & Cons

Pros

• Durable, textured urethane finish that provides impact and abrasion resistance for heavy use.
• Complete kit with base, hardener and spray gun makes setup straightforward for those with a compatible compressor.
• Weather, UV and waterproof properties protect surfaces and help prevent rust formation.

Cons

• Two-part mixing and spray application require some experience; absolute beginners may face a learning curve.
