RIRC Undercoating Spray Gun — 360° Flexible Wands, Suction Feed & Pressure Regulator for High‑Flow Rubberized Coatings

The RIRC Undercoating Spray Gun is a complete sprayer kit built to apply rubberized bed liners, chassis coatings and rustproofing quickly, evenly and with pro-level control.

This spray gun combines a high-flow suction cup feed, integrated pressure regulator and a 360° flexible extension to handle heavy rubberized coatings without thinning. Designed for both DIYers and professionals, the RIRC unit aims to reduce rework by filtering out debris, maintaining consistent spray pressure, and reaching tight vehicle cavities for full coverage.

How does this sprayer handle thick rubberized undercoatings?

The RIRC gun is engineered for high-viscosity materials: a 60% faster flow rate moves heavy coatings through the nozzle without frequent clogging or the need to thin products. The wide-mouth suction cup and larger internal passages let you refill and spray denser formulas while maintaining a steady output.

• 60% faster flow rate suited for unthinned rubberized materials
• Wide-mouth suction cup for fast refills and reduced spills
• Filter screen traps particles to prevent nozzle blockages
• Aluminum body tolerates thicker liquids without warping

Can I reach frames, cavities and awkward angles under the vehicle?

Yes — the kit includes two 360° flexible extension wands that let you direct the spray into frames, wheel wells and tight nooks without repositioning the vehicle. The flexible wand maintains a consistent spray pattern even when bent, enabling uniform coverage on hidden surfaces.

• Two flexible wands for different reach and angle needs
• Snap-lock suction cup keeps an airtight seal while tilted
• Consistent atomization through bends for even protection
• Better coverage reduces the need to reapply or touch up

How do I control texture and finish during application?

Control comes from the integrated pressure regulator and gauge, plus an adjustable nozzle that shifts from heavy coverage to finer atomization. You can dial in pressure while standing beside the vehicle, allowing immediate adjustments for texture, thickness and spray spread.

• Built-in pressure gauge for on-the-fly tuning
• Adjustable nozzle to switch between coarse and fine spray patterns
• Reduced overspray and more consistent finish with correct settings
• Compact regulator avoids constantly checking the compressor

What features help deliver a cleaner, more professional result?

The RIRC sprayer includes a filter screen cover to trap impurities before atomization, producing a smoother finish and fewer clog-related interruptions. Ergonomic design touches — a lightweight aluminum body, snap-lock suction cup and a cleaning brush in the kit — make long jobs less fatiguing and cleanup faster.

• Filter screen cover ensures ultra-fine finish and fewer specks
• Ergonomic grip and lightweight build reduces hand fatigue
• Snap-lock cup prevents messy leaks when working at angles
• Includes cleaning brush and manual for proper maintenance

Who is this for? The RIRC Undercoating Spray Gun is built for automotive shops, restoration enthusiasts and serious DIYers who need to apply rubberized coatings, bed liners, rustproofing or chassis protectants with speed and precision. It suits users who want a tool that handles heavy materials, reaches confined spaces, and delivers repeatable results without frequent clogging or guesswork about pressure settings.
