Custom Shop Urethane Spray-On Truck Bed Liner Kit, 1 gal Black — Textured Waterproof Coating with Gun & Hardener

Custom Shop U-Pol Raptor 1 gal spray-on kit is a professional-grade black urethane bed liner system that sprays on a rugged, waterproof protective coating and ships with an adjustable spray gun and regulator.

If you need to protect a truck bed, cargo box or metal surface from abrasion, corrosion and everyday wear, this ready-to-mix kit gives a textured, flexible urethane finish designed for utility and long life. The system uses a two-component formula: add the included hardener, shake, then spray with the Custom Coat bedliner spray gun. The cured coating resists stains, helps deaden road noise and holds up in salt, moisture and extreme temperatures without becoming brittle.

How does this kit make applying a spray-on bed liner easier?

The kit arrives with a pre-measured hardener and a Custom Coat spray gun fitted with an adjustable nozzle, regulator and gauge so you control flow and texture. Mixing is straightforward and the spray gun is tuned for thicker urethane formulations, reducing clogging and simplifying application for DIYers and pros.

• One-gallon base plus hardener — mix per instructions for correct pot life.
• Custom Coat gun includes regulator and pressure gauge for consistent spray.
• Adjustable nozzle for smooth or heavy textured finishes.
• Shake-and-spray workflow minimizes prep time between mixing and application.

What performance can I expect from U-Pol Raptor urethane coating?

The cured urethane forms a tough, flexible membrane that resists abrasion, staining and common environmental stressors. It’s formulated to protect metal against rust and corrosion while maintaining elasticity so it won’t crack under temperature swings or vibration.

• Abrasion- and stain-resistant surface suitable for heavy loads.
• Waterproof barrier that sheds moisture and prevents water intrusion.
• Flexible finish that dampens sound and reduces rattles.
• Formulation stands up to salt, damp conditions and wide temperature ranges.

How should I prepare my truck bed and apply the coating for best results?

Proper surface prep is key: remove loose rust, degrease, and scuff the surface to promote adhesion. Spray in even passes with overlap, keep the gun moving to avoid build-up, and allow full cure time before loading heavy cargo.

• Clean thoroughly of oil, wax, dirt and loose paint or rust.
• Sand or scuff glossy surfaces and apply primer where required.
• Apply thin, even coats with overlap; multiple coats build texture and thickness.
• Follow manufacturer cure times before full use and avoid moisture until cured.

Can I use the kit for applications beyond truck beds?

Yes — the urethane spray can protect trailers, tool boxes, ATV beds and industrial surfaces that need a rugged, non-slip coating. It’s useful wherever abrasion resistance and waterproofing are required and where a textured, durable finish is preferred.

• Trailers, flatbeds and cargo boxes for heavy-use protection.
• Tool chests and storage compartments to prevent dents and corrosion.
• Workshop floors or ramps where grip and impact resistance matter.
• Custom protective coatings on metal, wood and some plastics when prepped correctly.

Who is this for: The Custom Shop U-Pol Raptor 1 gal spray-on kit is aimed at truck owners, fleet managers, fabricators and DIYers who want a professional-grade, textured urethane liner without contracting out the job. It’s a strong choice if you need a waterproof, impact-resistant finish that reduces noise and stands up to heavy use; buyers should be comfortable with surface prep and basic spray technique to achieve optimal results.
