B4B BANG 4 BUCK HVLP Gravity Feed Spray Gun Kit — 1L Aluminum Cup, 3 Nozzles (1.4/1.7/2.5mm) & Regulator

B4B BANG 4 BUCK Professional HVLP gravity feed spray gun kit is a multi‑nozzle painting tool with a 1,000cc aluminum cup and regulator, built for controlled automotive and workshop finishes.

This HVLP (High Volume Low Pressure) gravity feed spray gun from B4B BANG 4 BUCK outfits hobbyists and professionals with three stainless steel nozzle sizes, a large 1L aluminum cup, and a true micrometer air regulator with gauge for repeatable, controlled spraying. Lightweight and ergonomically balanced, the set aims to reduce fatigue during extended use while offering precise adjustment over pattern, fluid and air. It’s supplied with the most commonly used nozzle preinstalled and includes the wrench, barb tail and spare parts needed to get started.

How does the nozzle selection affect my finish?

Different nozzle sizes change atomization and material flow, so choosing the right tip for your coating and job size improves finish quality. Use smaller nozzles for fine detail and thinner materials, and larger nozzles for higher viscosity coatings and faster coverage.

• 1.4mm nozzle: best for thin primers, enamels and detailed touch-ups.
• 1.7mm nozzle: versatile mid‑range tip for base coats and most lacquers.
• 2.5mm nozzle: suited to high‑build primers, gel coats and heavy coatings.

What controls let me dial in consistent spray patterns?

The gun has three primary adjustment points—spray pattern, fluid volume and air pressure—so you can tune atomization and coverage. The included true micrometer air regulator with gauge provides reliable pressure readings for repeatable setups between passes or projects.

• Spray pattern knob: switch from narrow to wide fan shapes for edges or broad panels.
• Fluid control: fine‑tune paint flow to prevent runs or to increase build.
• Air regulator with gauge: set and monitor working pressure for consistent results.

What materials and projects is this spray gun suitable for?

This kit is designed to handle a broad range of automotive and workshop coatings, from base and clear coats to thicker primers and specialty compounds. The stainless steel needles and nozzles withstand harsher materials while the gravity feed cup reduces wasted paint and simplifies cleaning.

• Automotive: base coats, clear coats, touch‑ups and topcoats.
• Primers and heavy coatings: high‑build or polyester primers, chip guard.
• Specialty applications: gel coats, liquid mask, metal flakes and thick enamels.

How easy is it to set up, clean, and maintain?

Out of the box the most common nozzle is preinstalled and tightened for airtightness; occasional firm effort may be needed to remove it. Routine maintenance is straightforward—flush with compatible solvent, wipe the cup and needle, and inspect seals—to keep spray performance consistent.

• Included wrench and barbed tail simplify disassembly and hose attachment.
• Aluminum 1000cc cup screws on for quick refills and easy cleaning.
• Stainless steel needles resist corrosion, extending service life.

Who is this for: The B4B BANG 4 BUCK HVLP gravity feed spray gun kit fits body shops, refinishing pros, restorers and advanced hobbyists who need a versatile, cost‑effective sprayer able to handle both fine finishing and higher‑viscosity coatings. If you value a large cup capacity, multiple nozzle sizes, and a reliable pressure regulator for consistent results, this set provides the core components to tackle panel repairs, full panels and specialty coating jobs without investing in separate guns for each task.
