U-POL Raptor Spray-On Bed Liner Kit — 4-Quart Black, 2K Urethane UV-Resistant Protective Coating

This ready-to-use kit supplies four 24 oz. bottles of black urethane base, one 32 oz. hardener, and a spray gun so you can mix, shake, and apply a durable textured coating yourself. Formulated as a 2K urethane, it bonds to well-prepared metal, painted panels, fiberglass, concrete and wood, offering weather resistance and long-term wear without specialized bodyshop equipment.

How much area will one 4-quart kit cover?

One 4-quart Raptor kit covers about 125 square feet when applied at typical thickness and texture—generally enough for a standard 6-foot truck bed. Coverage varies with surface porosity and the texture you choose; heavier textures or multiple coats reduce total square footage covered per kit.

• Approximate coverage: 125 sq. ft. per 4-quart kit
• Standard truck bed (6 ft): usually covered by one kit
• Thicker texture or two-coat jobs: plan on extra kits
• Porous or rusted surfaces may need primer or more material

Can I use this coating on surfaces other than a truck bed?

Yes—when substrates are properly prepared, this urethane adheres to sanded OEM paint, bare metal, aluminum, fiberglass, wood and concrete. That versatility makes it suitable for trailers, garage floors, boat decks, fender wells and underbody protection in addition to truck beds.

• Adheres to: sanded paint, bare metal, aluminum, fiberglass, wood, concrete
• Common uses: trailers, decks, floors, off-road gear, undercoating
• Preparation: degrease, sand, and remove loose rust or contaminants
• Optional additives: skid-resistant granules for traction

Is the kit suitable for DIY application and what tools do I need?

The kit is designed for consumer use with a simple 3:1 mix ratio—add 8 oz of hardener to each 24 oz bottle, shake, and spray. The included spray gun works with compressors around 8 CFM at 50–60 PSI; you can also roll or brush for different textures and touch-ups.

• Mixing: 3:1 base to hardener; add 8 oz hardener per bottle
• Application methods: spray (included gun), roller, or brush
• Recommended compressor: ~8 CFM at 50–60 PSI for best spray
• Drying: tack-free about 1 hour; light use in 2–3 days; full cure 5–7 days

Will this finish stand up to sun, chemicals and heavy use?

Formulated as a 2K urethane with UV resistance, the coating resists fading and holds up to chemicals, abrasion and impact better than many single-component coatings. Properly applied, it flexes with substrates to prevent cracking or peeling while also reducing noise and protecting against rust.

• UV resistant: helps maintain deep black color outdoors
• Chemical and abrasion resistance: resists stains and physical wear
• Durability: flexible film reduces cracking and peeling
• VOC compliance: meets 50-state requirements

Who is this for: The U-POL Raptor 0820VG 4-quart kit is aimed at vehicle owners, DIY mechanics and small fleet operators who want a robust, long-lasting protective coating without a professional shop. It also suits hobbyists restoring trailers, boat owners protecting decks, and homeowners looking for a resilient surface on ramps or garage floors. If you need a sprayable, UV-stable, 2K urethane solution that bonds to many substrates and can be textured for traction, this kit offers a balanced mix of performance and user-friendly application.
