Custom Shop Urethane Spray-On Truck Bed Liner Kit Black 2 Gallon — 3:1 Mix, Textured Durable Coating

Custom Coat Black 2 Gallon is a two-part urethane spray-on truck bed liner kit that delivers a textured, durable protective coating with a simple 3:1 mix-and-spray application.

This kit bundles everything needed to coat about 110–130 sq ft at a 10 mil wet film thickness: eight 24 fl. oz. cans of black base, eight 8 fl. oz. cans of standard hardener, plus a dedicated applicator spray gun and regulator. Designed for DIYers and pros alike, the formulation balances flexibility and toughness to protect metal, wood, concrete and other surfaces from abrasion, moisture and UV exposure while also reducing noise and vibration.

How do I mix and apply the 3:1 Custom Coat kit?

Mixing is straightforward: combine three parts base to one part hardener, shake thoroughly, then load the supplied spray gun. Apply in even passes, keeping about 8–12 inches from the surface, and build coats to the desired thickness. Clean the gun immediately after use to maintain performance.

• Mix ratio: 3 parts base : 1 part hardener (by volume).
• Shake or agitate mixture well for uniform color and cure.
• Spray distance: ~8–12 inches; maintain even overlapping strokes.
• Tool cleanup: flush gun before material cures.

What surfaces and projects is this urethane coating best for?

Custom Coat works on truck beds, vehicle exteriors, trailers, bumpers and chassis as well as home surfaces like garage floors, docks and wooden decks. Its textured finish improves grip on walkways and steps, while the flexible urethane resists chipping where some rigid coatings fail.

• Automotive: truck beds, bumpers, toolboxes, undercarriage components.
• Commercial equipment: trailers, heavy machinery, utility beds.
• Residential: concrete floors, stairs, decks, docks, tubs and walls.
• Non-skid applications: ramps, steps and high-traffic walkways.

How long does it last and what environmental conditions can it handle?

The urethane formulation resists UV degradation, heat and water, giving long-term protection against rust and surface wear when properly applied. While longevity depends on surface prep and usage, the product is made to withstand temperature shifts and outdoor exposure without brittle failure.

• Waterproof and UV-resistant to minimize fading and moisture damage.
• Flexible enough to tolerate thermal expansion and impacts.
• Helps dampen sound and vibration for a quieter ride or workspace.
• Durability depends on correct surface prep and application thickness.

What finish and color options are available for customization?

This kit ships in black, providing a classic textured finish ideal for concealment and utility. Custom Coat also offers urethane tint concentrates in over 50 colors for multi-tone or camouflage finishes, and kits are available in different sizes and application styles for spray or roller use.

• Standard kit color: black textured finish for durability and concealment.
• Tint concentrates: available in 50+ colors for custom looks.
• Application options: spray gun (included) or roller kits sold separately.
• Available sizes: from 1 quart up to 2 gallon kits to match job scale.
