U-POL Tintable Raptor Urethane Spray-On Truck Bed Liner Kit — 4L with Free Spray Gun, UV-Resistant Durable Finish

This kit combines a tintable base, a urethane hardener, and an applicator gun to create a textured, waterproof protective layer for truck beds, cargo areas, and other vehicle surfaces. Designed to bond to most OEM paint and self-etching primers, the formula dries quickly, resists stains and abrasion, and reduces road noise and vibration while remaining flexible under temperature changes.

How easy is the U-POL Raptor kit to apply?

Application is straightforward for anyone comfortable using a compressed-air spray gun. Fill the base bottles to the marked line with the supplied hardener, shake thoroughly, and spray with even sweeping passes; you can also roll or brush for alternative textures.

• Includes an application spray gun (requires ~8 CFM at 50–60 PSI)
• Mix by adding hardener to the fill line, then shake the bottle
• Apply 1–3 coats; recoat after 60 minutes if needed
• Can be rolled or brushed for different finishes

What performance can I expect once cured?

The cured urethane film is designed for long-term protection: it resists scratches, staining, and UV fading while remaining flexible to withstand impacts and temperature swings. It also helps dampen sound and vibration when applied as an undercoating or inside vehicle cavities.

• Scratch- and stain-resistant surface that tolerates outdoor exposure
• UV-resistant formulation to minimize fading over time
• Flexible finish that resists cracking in temperature extremes
• Sound-deadening properties for reduced road noise

How much area does one 4-liter kit cover and what are the cure times?

This 4-liter kit produces approximately 1.06 US gallons of finished coating and covers about 125 square feet—roughly an 8-foot truck bed with standard film build. Drying and service times depend on film thickness and ambient temperature.

• Coverage: ~125 square feet (standard 8 ft bed)
• Pot life at 68°F: ~60 minutes after mixing
• Touch dry: under 1 hour depending on build; light-duty use in 2–3 days
• Regular-duty use typically after 5–7 days for full durability

Preparation is essential: surfaces should be clean, scuffed or lightly sanded, and free of rust and contaminants for optimum adhesion. If you encounter bare metal, prime it first with an appropriate self-etching or acid primer before applying the Raptor system.

Who is this for? Automotive enthusiasts, fleet managers, and DIYers who want a durable, tintable spray-on bed liner that protects against abrasion, weathering, and noise will find this kit ideal. It’s suited for truck owners restoring or upgrading cargo areas, professionals needing a reliable coating for utility vehicles, and hobbyists who want a textured, long-lasting finish with the flexibility to tint to match or accent vehicle color. Always follow safety guidance and local regulations when using two-component urethane systems.

• Scratch and stain resistant
• Helps deaden sounds and vibrations
• UV Resistant - Will not fade
