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

In this review of the Custom Coat GM White 1 Gallon Urethane Spray-On Truck Bed Liner Kit, the bottom line is simple: it is aimed at DIYers and small shops who want a professional, durable textured coating with tinting options and the included spray gun. The kit stands out because it bundles tintable base, hardener, basecoat tints and a regulator-equipped applicator, making it possible to mix, tint and spray a one-gallon, two-part urethane coating that resists UV, heat and water while helping prevent rust and dampen noise.

Key Features

• Complete 1 gallon kit: Includes four cans of tintable base, four hardener cans, four tint bottles and a spray gun with regulator so users get everything needed to mix and apply a single-gallon system.
• Tintable color options: The included basecoat tints let you create a custom color or camouflage look rather than being limited to a single factory shade.
• Durable urethane formula: The heavy duty 2-part urethane provides a flexible, textured finish that resists chipping and offers impact and abrasion protection.
• Weather resistant protection: Heat, UV and waterproof properties help protect metal surfaces from rust and reduce vibration and road noise.
• Good coverage: Estimated coverage of 110 to 130 sq ft at 10 mils wet film thickness makes the kit suitable for a standard truck bed or multiple small projects.
• DIY friendly application: The supplied spray applicator with regulator is sized for home compressors and helps achieve a professional sprayed texture with less equipment hassle.

Who It's For

This kit is best for hands-on vehicle owners, hobbyists and small shops who want a professional-looking, textured truck bed liner without outsourcing the job. It is also well suited for people who want to tint their liner to match or customize their vehicle or equipment.

Those who should look elsewhere include users who need larger coverage than one gallon provides for multiple vehicles or full-vehicle coatings, and buyers who prefer pre-mixed single-component roll-on systems rather than a 2-part mix-and-spray process.

Pros & Cons

Pros

• All-in-one kit includes base, hardener, tints and a spray gun, making setup straightforward for DIYers.
• The urethane texture is flexible and provides good impact and abrasion resistance for truck beds and equipment.
• Tintable formula offers customization and a choice of colors for camo or matching finishes.

Cons

• One gallon limits coverage for larger projects, so multiple kits are needed for full-vehicle jobs.
• Durability reports are mixed among users, so exact long-term chip resistance may vary with prep and application technique.
