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

In this review of the Custom Coat GM White 1 Quart Urethane Spray-On Truck Bed Liner Kit, the bottom line is simple: this kit is for DIYers who want a professional-looking, durable textured coating without complex mixing. The reviewer found it especially useful for small projects like single truck beds, bumpers, tool boxes or concrete steps where long-lasting UV and heat resistance matter. The kit's easy mixing and tintable base deliver a flexible, impact-resistant finish that helps prevent rust and dampens vibration.

Key Features

• Complete 2-part kit: Includes a 21 fl. oz. base, an 8 fl. oz. standard hardener and a 3 fl. oz. tint bottle so a full small application can be completed without buying extra components.
• Tintable color: The included basecoat tint lets users match or customize color for a single solid look or multi-colored effects and camouflage patterns.
• High coverage: Estimated coverage of 110 to 130 sq ft at 10 mils wet film thickness makes this kit economical for one-vehicle or small-area projects.
• Durable urethane formula: The heavy duty 2-part urethane gives impact and abrasion resistance while remaining flexible to resist chipping.
• Weather and water resistance: Heat, UV and waterproof properties protect coated surfaces from rust and exterior wear.
• Sound damping: The textured finish helps reduce road noise and vibration when applied to truck beds and equipment.

Who It's For

This kit is best for hands-on vehicle owners, hobbyists and small shops who want a professional spray-on textured bed liner without contracting the job. It suits users who need a flexible, UV-resistant coating for truck beds, bumpers, trailers, tool boxes and even non-skid home surfaces like steps and garage floors.

Those who should look elsewhere include people needing large-scale industrial quantities or multi-gallon jobs where a larger kit would be more economical, and users who prefer a roller-only application set rather than a spray setup.
