ENDOZER Professional HVLP Spray Gun Set Gravity Feed Air Spray Gun with 1.4, 1.7, 2.0mm Nozzles 20oz 600cc with Gauge for Auto Paint, Primer, Clear/Top Coat & Touch-Up

Why I reached for this gun

I’ve got a small stable of HVLP guns for different tasks, but I wanted a budget-friendly setup that could handle primer, base, and clear without swapping guns. The Endozer HVLP spray gun set, with its 600 ml cup and three stainless nozzles (1.4, 1.7, 2.0 mm), looked like the right kind of versatile. After several sessions—automotive base/clear on a panel, high-build primer on parts, and an exterior wood stain job—I have a solid feel for where it shines and where it compromises.

Build and design

The core components are better than I expect at this price. The stainless needle/nozzle sets have held up to solvent cleaning without staining or pitting, and the brass air cap’s 15-hole pattern produces a soft-edged fan that’s easy to tune. Controls are the familiar trio: fluid, fan pattern, and an air valve at the gun. The included mini regulator/gauge mounts at the handle and is a practical touch; I prefer setting pressure at the gun rather than walking back to the compressor.

The gun is gravity feed with a 600 ml (20 oz) cup—enough for panels, small jobs, and coat-by-coat refills on larger work. The body machining is clean, threads are smooth, and the trigger pull is light and predictable. The 1/4" NPT inlet with a quick adapter drops right into standard shop setups. You also get a mesh paint filter and some basic tools.

One note on assembly: the factory-installed nozzle on my gun was on the snug side. I broke it loose carefully with the supplied wrench after warming the tip for a few seconds and had no issues afterward. I now oil those threads lightly before reassembly to avoid galling.

Setup and tuning

With HVLP, setup is half the battle. Here’s what worked well for me:

• Air: I run pressure at the gun regulator with the trigger pulled. Most of my solvents (base and clear) were happy in the mid-20s psi at the cap; thicker primers wanted a bit more. Always check the coating’s tech sheet and do a test pass.
• Nozzles: the 1.4 mm is my base/clear go-to, the 1.7 mm covers medium-solids primer and sealer, and the 2.0 mm can push heavier primers and stains. If you’re tempted to push interior latex, don’t—this gun isn’t built for that. If you must spray heavier waterborne coatings, plan on aggressive thinning and expect extra cleanup.
• Pattern: I start with a wide fan and back down only if I need to fit into tight spots. The brass cap keeps an even atomization across the fan at appropriate pressures.
• Filtration: use the included cup filter and strain every batch of paint. This alone saves clogs and surface nibs.

The included gauge is handy but, like most gun-mounted minis, not lab-grade. Mine read a couple psi different from my inline reference regulator. Close enough—just be consistent.

Performance in the booth (and the backyard)

On a test hood and panel, the Endozer laid down base coat cleanly with the 1.4 mm setup. Atomization was uniform, edge build was controllable, and I didn’t fight tiger striping or spitting. Clear coat went on with minimal texture once I dialed in overlap and gun speed—two medium-wet coats followed by a wetter third produced a finish that needed only a mild nib sand and polish. This isn’t a boutique pro gun, but the results were absolutely presentable for hobbyist automotive work.

For primer, swapping to the 1.7 mm let me push a high-build primer-surfacer with reasonable reduction. The fan stayed stable, and the gun didn’t starve for air when fed by a mid-size shop compressor. With the 2.0 mm, I sprayed an exterior oil-based stain on a backyard play structure. The wide fan and controlled fluid let me cover quickly, then I back-brushed for penetration. That job would’ve been a day or two with a brush; it became an afternoon with the gun.

Overspray is on par with other HVLPs; the cap does a good job keeping the pattern soft. Keep your technique tight—6–8 inches off the work, 70% overlap, and maintain speed—and you’ll get consistent results.

Ergonomics and maintenance

This gun is comfortable for long passes. The trigger is smooth with a predictable break, and the balance with a half-full cup feels neutral. The knurled adjustment knobs are easy to turn with gloved hands, and I didn’t experience drift once set.

Cleaning is straightforward. I can fully strip the gun—needle, nozzle, cap, and fluid passages—in a few minutes. The kit includes a basic brush; I’d suggest picking up a small gun-cleaning brush set and dedicated picks to get into the cap holes and fluid passages properly. As with any HVLP, I flush with the appropriate reducer immediately after a session, then break it down for a quick wipe and relube of the needle and threads.

One practical tip: use the paint filter every time and keep those air cap holes clear. A tiny bit of dried material in the cap will distort the pattern more than you’d expect.

Limitations and quirks

• Not for thick latex. The manufacturer is clear on this, and I agree. Even with the 2.0 mm, interior acrylic latex will be a fight. Automotive, furniture finishes, stains, and solvent-borne coatings are its wheelhouse.
• Gauge accuracy is “good enough,” not perfect. Treat it as a relative reference and develop a feel for your ideal setting.
• Nozzle swap tightness. The factory nozzle on mine needed careful persuasion to remove the first time. Break it loose thoughtfully and you’ll be fine.
• Needle packing. The needle packing on this gun isn’t user-adjustable in the typical “packing nut” sense. My unit stayed dry at the trigger with both thin and thicker materials, but if you see weeping with very thin reducers, stop, clean, and inspect the needle/seat and seals before continuing.
• Instructions are minimal. If you’re brand new to HVLP, plan to watch a few setup videos to understand air-on/trigger-on pressure checks, fan tuning, and distance/speed.

Who it’s for

• DIYers and hobbyist auto refinishers who want one kit to handle primer, base, and clear on panels and small-to-medium projects.
• Woodworkers and refinishers spraying stains, sealers, and clear coats.
• Pros needing a capable backup or dedicated primer gun without sinking pro-gun money.

If you’re shooting production volumes daily, premium guns still earn their keep with finer atomization at lower pressures and tighter QC. But for most project-focused users, the Endozer’s performance is more than good enough.

Tips that improved my results

• Strain every material into a clean cup and keep a lid on the mix between coats.
• Set pressure at the gun with the trigger pulled; mark the sweet spot on the regulator body.
• Start with the fluid backed out 1.5–2 turns from closed and adjust by half turns after a test panel.
• Use the right nozzle for the job: 1.4 for base/clear, 1.7 for most primers/sealers, 2.0 for heavier primers and stains.
• Clean immediately after use; don’t let material dry in the passages or cap.

Pros and cons

Pros:
- Three stainless nozzle/needle sets included (1.4/1.7/2.0 mm) cover most tasks
- Brass 15-hole cap provides even atomization and a predictable fan
- On-gun regulator/gauge simplifies pressure dialing
- Easy teardown and cleaning; smooth controls and comfortable trigger
- Strong results with automotive base/clear and primers at a budget price

Cons:
- Not suited to interior latex; heavy waterborne materials demand heavy reduction
- Minimal documentation; beginners will need outside guidance
- Occasional factory-tight nozzle; take care on first disassembly
- Needle packing isn’t user-adjustable; rare chance of weeping with thin materials
- Included cleaning tools are basic; a dedicated brush kit helps

Recommendation

I recommend the Endozer HVLP spray gun set for hobbyists, DIYers, and budget-conscious pros who want a capable, versatile gun with multiple nozzle options in the box. It produces a consistent fan, atomizes well enough for clean base/clear work, and swaps effortlessly into primer and stain duties with the 1.7 and 2.0 mm setups. You’ll trade some refinements you’d get from high-end guns—documentation, top-tier gauge accuracy, and long-term QC consistency—but with good technique and proper cleaning, it delivers results that punch above its price. If you primarily spray thick latex, look elsewhere. For automotive panels, furniture finishes, and general project work, this set is a smart, cost-effective addition to the shop.
