Custom Shop U-Pol Raptor Tintable Urethane Bed Liner Kit - 4 Quart Kit

In this review of the Custom Shop U-Pol Raptor Tintable Urethane Spray-On Truck Bed Liner Kit, the bottom line is simple: it is for truck owners and DIYers who want a durable, factory-like protective coating and the convenience of tinting. The kit pairs a 4-quart tintable base with the required hardener and includes a Custom Coat bedliner spray gun with regulator and gauge, so most buyers get everything needed to mix, spray and protect bed surfaces. The single biggest reason to buy is the combination of ease of use and proven protection against rust, corrosion and abrasion.

Key Features

• Tintable Formula: The U-Pol Raptor base accepts up to 10% of base color for a customized finish that matches or complements the vehicle.
• Complete Kit: Four 711 ml bottles of tintable base plus a quart of standard hardener provide the correct 3:1 mixing ratio for a full 4 quart system.
• Included Spray Gun: The Custom Coat bedliner spray gun arrives with an adjustable nozzle, regulator and gauge to improve spray control and consistency.
• Durable Protection: The urethane coating resists abrasion, stains, rust and corrosion, helping protect metal, fiberglass and other substrates.
• Weather Resistant: The waterproof, flexible finish helps deaden sound and withstand salt, damp and extreme temperatures.

Who It's For

The kit is aimed at hands-on truck owners, body shops and automotive DIYers who want a professional-looking, textured bedliner without hiring a commercial shop. Because the product is tintable and comes with a bedliner gun, it suits users who want color-matched results and prefer to control application.

Those who should look elsewhere are buyers seeking a waterborne, single-component spray or a no-mix aerosol option; this is a 2K urethane system that requires mixing hardener and attention to pot life and spraying technique.

Pros & Cons

Pros

• Provides a factory-like textured finish that many users say looks professional and holds up to heavy loads.
• Tintable base lets you add up to 10% base color for a closer match to vehicle paint.
• Includes a Custom Coat bedliner spray gun with regulator and gauge to reduce overspray and improve control.

Cons

• As a 2K system, it requires correct mixing and technique; novices may need practice to avoid runs or uneven texture.
• Some customers report long-term cracking or peeling in heavy-use scenarios, so surface prep and application quality matter.
