Custom Shop Black Urethane Spray-On Truck Bed Liner 2 Quart Kit

In this review of the Custom Shop Black Urethane Spray-On Truck Bed Liner 2 Quart Kit with Hardener, the bottom line is simple: this kit is aimed at DIY truck owners who want a factory-like, rugged bed coating without professional labor costs. The reviewer finds the product most compelling for its straightforward 3:1 mixing and spray workflow: add the hardener, shake, and spray with the supplied bedliner gun. Ease of application combined with abrasion and UV resistance make it a reliable option for restoring or protecting a pickup bed from rust, salt, and heavy cargo.

Key Features

• Two-part urethane formula: A 2K protective coating that delivers a tough, durable finish designed to resist abrasion and stains under heavy use.
• Complete 2 quart kit: Includes four 711 ml bottles of black base and a quart of standard hardener, providing enough material to recoat the largest truck beds without running short.
• Spray-ready system: The Custom Coat Bedliner spray gun has an adjustable nozzle plus regulator and gauge, allowing finer control over texture and minimizing overspray.
• Weather and corrosion protection: Formulated to protect against rust, corrosion, salt, damp and extreme temperatures for long-term exterior durability.
• Waterproof and sound damping: The flexible urethane finish helps seal surfaces against water and dampens noise and vibration from cargo.

Who It's For

The kit is best for hands-on truck owners, hobbyist installers, and small shops that prefer to apply their own bedliner with a spray gun rather than paying for professional installation. It is ideal for those who value a factory-like textured finish, UV resistance, and strong protection from abrasion and corrosion.

Those who should look elsewhere include owners wanting a single-component, no-mixing product or someone unwilling to work with a two-part urethane and the required safety precautions. Also consider a professional installation if you need a guaranteed, long-term commercial warranty against peeling in extreme-use scenarios.

Pros & Cons

Pros

• High durability and abrasion resistance for hauling heavy cargo like wood and drywall.
• Includes a purpose-built spray gun with regulator and adjustable nozzle for controlled application and good sprayability.
• Waterproof, flexible finish that helps prevent rust and reduces cabin noise from vibrations.
• Kit size is generous and should cover large truck beds without needing extra purchases.

Cons

• As a two-part urethane, proper mixing and application technique are required; some users reported cracking or peeling over long term in heavy-use cases.
• Requires spray equipment handling and safety precautions, so not truly 'no-prep' for novices.
