TCP Global Air Undercoating Spray Gun with Gauge - 22-Inch Extension Wands

Meet the TCP Global Air Undercoating Spray Gun with Gauge, a purpose-built pneumatic tool designed for automotive coatings. Built to apply rustproofing, undercoating, bed liner, chip guard, and related coatings, it combines tactile control with practical reliability, making it a solid option for both professional shops and DIY projects.

Versatility that adapts to your project

The kit supports a range of coatings — oil-based, solvent-based, and water-based — so you can choose the right material for each job. The combination of an aluminum body and a compact air regulator helps you manage spray quality as you work around wheel arches, frame rails, and truck beds.

• Two 22-inch extension wands extend your reach into hard-to-access areas
• One extension wand features a multi-directional nozzle for flexible spray patterns
• One straight nozzle provides direct, focused application
• 25-ounce suction feed aluminum cup keeps coatings contained and reduces drift

Precision, texture, and control you can feel

The gun is lightweight, balanced, and machined for consistency. It handles coatings with different viscosities and textures, while the built-in gauge helps you monitor air pressure and maintain a steady spray. This makes it easier to achieve even coats without sagging or pinholes.

• Ergonomic trigger grip minimizes fatigue over long sessions
• Machined components deliver reliable texture across passes
• Varied viscosity coatings spray smoothly for uniform appearance
• Gauge-based regulation supports predictable results

Durable build for professional and DIY use

Designed with a die-cast aluminum alloy body, the tool withstands regular use in garages, shops, or job sites. The durable construction pairs with a comfortable grip for prolonged work; and the gauge-equipped regulator helps you stay in the safe operating zone as you work around critical areas.

• Die-cast aluminum body resists corrosion and wear
• Comfortable grip reduces hand fatigue during extended sessions
• Integrated air regulator with visible gauge for pressure awareness
• Suction cup design minimizes mess and overspray

Real-world use often involves tackling underbody rust protection, wheel wells, and bed rail coatings. This gun’s extended reach and textured spray options support careful, controlled coverage. Always follow coating manufacturer directions and safety guidelines for best results.
