Custom Shop Urethane Spray-On Truck Bed Liner Kit — Black 2-Quart, 2K Hardener Included, Durable Textured Finish

Custom Shop Black Urethane Spray-On Truck Bed Liner 2 Quart Kit is a two-component urethane coating designed to protect and texture truck beds, metal, wood, concrete and fiberglass surfaces.

This complete kit contains everything needed to coat large truck beds: four 711 ml bottles of black urethane base and one quart of Raptor standard hardener. Formulated as a low-VOC 2K urethane, it cures into a flexible, waterproof textured finish that resists abrasion, stains, and environmental corrosion. Raptor-style systems are compatible with spray guns, rollers, and brushes and offer strong adhesion to most OEM finishes when surfaces are properly prepared.

How do I mix and apply this two-part bed liner?

Mixing follows a straightforward 3:1 ratio—three parts liner base to one part Raptor standard hardener. After combining, shake thoroughly to emulsify the components, then apply while the mixture is fresh. You can spray with a dedicated bedliner gun for professional texture or use a roller/brush for spot repairs and smaller areas.

• Kit contents: 4 × 711 ml black base bottles + 1 quart hardener
• Mix ratio: 3:1 base to hardener
• Application methods: bedliner spray gun, roller, or brush
• Shake mixture well before use; follow gun manufacturer settings

Will this coating protect my truck bed from rust, chemicals, and impact?

This urethane formulation forms a durable, flexible membrane that blocks moisture and resists common chemicals, abrasion and staining. It helps prevent corrosion of the underlying metal when applied to clean, de-rusted surfaces and adheres well to properly prepared substrates. Avoid making absolute durability guarantees; real-world longevity depends on surface prep, application technique, and exposure conditions.

• Waterproof and flexible to accommodate shocks and temperature swings
• Resists abrasion, stains, salt and many common chemicals
• Helps deaden sound and vibration for quieter loads
• Best performance over clean, scuffed, or primed metal

What surface prep and primer do I need before using this kit?

Good adhesion starts with a clean, dry surface free of dirt, oil and loose rust. Lightly scuff glossy factory paint to promote mechanical adhesion; bare metal should receive an appropriate etch primer to prevent flash rust and improve bonding. Follow primer manufacturer instructions and allow full cure before applying the urethane mix.

• Remove grease, wax and contaminants with suitable cleaners
• Lightly scuff OEM finishes for better adhesion
• Treat bare metal with an etch primer (e.g., Acid#8 / UP0776/UP0741)
• Ensure surface is dry and dust-free prior to coating

How much coverage will the 2 quart kit give and can I tint it?

The combined volume of this kit is sized to cover the largest standard truck beds when applied at typical textured thicknesses; actual coverage varies with application technique and texture preference. This listing is for black pre-colored liner; tintable options are offered separately for custom colors. When aiming for full bed coverage, plan on using the full kit and follow recommended film thickness for best results.

• Kit sized for large truck beds at standard textured application thickness
• Coverage depends on spray pattern, texture and number of coats
• Black finish included; tintable variants sold in separate listings
• Use entire kit for even, consistent results on large beds

Who is this for? This two-part urethane kit suits vehicle owners, professional installers and DIYers who want a hard-wearing textured finish for truck beds, utility trailers, toolboxes, or hard-wearing floors. It’s best for users comfortable with mixing 2K systems and following surface-prep and safety steps; those seeking custom colors or smaller touch-ups may prefer separate tintable kits or sample sizes.
