U-POL Raptor spray-on truck bed liner — Black 4L, 2K urethane, UV- and impact-resistant

This kit contains everything needed to coat an 8' truck bed with a textured, impact-resistant finish that stands up to abrasion, chemicals, and weathering. The fast-curing, tintable formula bonds to OEM paint or self-etching primer, remains flexible to reduce vibration and noise, and retains color long-term thanks to UV resistance. It’s supplied as a complete 2K system with base, hardener, and simple application options for spray, roll, or brush.

How quickly will the Raptor kit be ready to handle traffic?

The Raptor urethane cures rapidly, allowing multiple coats within an hour so you can finish a full system in a single day. Tack-free times are short, and a cured surface provides immediate resistance to light contact while reaching full mechanical strength over time.

• Rapid-dry formula accommodating back-to-back coats.
• Fast initial set reduces downtime between layers.
• Handles light use soon after curing, full hardness develops later.
• Designed for single-day projects on typical truck beds.

What levels of protection does this coating provide?

This 2K urethane forms a waterproof, corrosion-resistant barrier engineered to resist scratches, stains, impact and many chemicals. The flexible nature of the cured film helps absorb shock and reduces the chance of cracking or flaking under heavy use.

• Resists abrasion, staining and common chemicals.
• Waterproof seal that protects metal from rust.
• Impact-tolerant, flexible finish reduces vibration.
• UV-stable tint prevents visible fading over time.

How easy is application for a DIYer versus a pro?

The kit is designed for both professional and competent DIY installers. It includes four 750ml base bottles and one 1L hardener with instructions; you can spray using the supplied gun for a professional texture or roll/brush for custom finishes and touch-ups.

• Comes with parts and instructions for straightforward mixing.
• Included spray gun speeds large-area coverage.
• Roll or brush application possible for edges and repairs.
• Covers approximately 125 sq. ft., sufficient for an 8' bed.

Will the coating stick to my vehicle’s surface?

The Raptor system bonds reliably to OEM paint and to self-etching primers when proper surface preparation is followed. Good adhesion requires cleaning, de-greasing and, where needed, light abrasion or primer to ensure the coating mechanically keys to the substrate.

• Bonds directly to OEM paint when surfaces are prepared.
• Works especially well over self-etching primer for metal.
• Surface cleaning and scuffing improve adhesion and longevity.
• Instructions specify mix ratios and prep steps for best results.

Who is this for: The U-POL Raptor Black 4L kit suits truck owners, fleet managers and fabricators who need a robust, long-lasting protective coating for beds, trailers, underbodies and marine or utility surfaces. It’s aimed at users who want professional-grade durability with the flexibility to spray for factory-like texture or roll/brush for detailed or small-area work. If you need a waterproof, impact-resistant finish that keeps color under sunlight and reduces road noise while protecting against corrosion and wear, this kit is engineered for that purpose.
