We've all been there. The glue-up went well, the sanding is done, and the only thing standing between you and a finished piece is the topcoat. You brush it because that's what you have, and it looks fine until a low kitchen light catches the panel at the wrong angle and every stroke shows up like a signature you didn't mean to leave.
That's usually the moment somebody starts pricing spray equipment, and the internet hands you a list of five machines with five buy buttons under them. I wanted to do something different here: hold the finish still and look hard at the machines. The finish is General Finishes High Performance, a water-based acrylic/urethane blend.
One honest thing up front. I went looking for a published side-by-side test spraying the same waterborne poly through a cheap handheld, a mid-range Earlex, and a Fuji, and I could not verify that such a test exists. So I'm not going to describe spray-outs I can't stand behind. What I can do is read the published specs against the finish maker's own published spec, and that turns out to be a blunter story than any spray-out would have been.
The one number on the data sheet that settles most of it
General Finishes' technical data sheet for High Performance, dated April 2019, calls for an HVLP spray tip of 1.1mm to 1.3mm. That isn't a stray figure. General Finishes' "How Do I Spray Water Based Finishes?" FAQ repeats 1.1–1.3mm for High Performance, Flat Out Flat, Enduro-Var II, water-based stains, Enduro Clear Poly, pre-cat lacquer and conversion varnish. It's a house-wide number for their thin clears. The same TDS puts the viscosity at 350–450 cPs and solids at 25% by weight and volume.
Now hold that against what each machine can actually be fitted with. Prices below were read in August 2026 from the retailer pages named, and those pages carry no date stamps, so treat them as what was showing that week rather than a price history.
| Machine | Price as read | Tip installed | Tips offered | Hits 1.1–1.3mm? |
|---|---|---|---|---|
| HomeRight Super Finish Max | $57.00 (WoodArtSupply), $79.99 (HomeRight) | 2.0mm | 1.5 / 2.0 / 4.0mm | No |
| Earlex 3700 handheld | $100.00 (Wagner) | 2.0mm | 1.5 / 2.0 / 4.0mm | No |
| Earlex 5700 | $360.00 (Wagner) | 1.5mm | 1.5 / 2.0 / 2.5mm | No |
| Fuji Semi-PRO 2 | $569.00 (Woodcraft) | 1.3mm | 0.8mm–2.0mm | Yes |
| Earlex 6700 | $650.00 (Wagner), $649.99 (Rockler) | 1.3mm | 0.8 / 1.3 / 1.8 / 2.2mm | Yes |
Three of those five cannot be set to the finish manufacturer's spec at any price, because the parts don't exist. That's not an opinion about build quality. It's a parts catalogue.
Reasoning from those numbers rather than from a test: a 2.0mm tip on a 1.8–2.2 PSI machine is being asked to atomize a 350–450 cPs coating whose maker says it wants 1.1–1.3mm.
Stage count is not the number you're actually buying
The standard advice is to count turbine stages. Pittsburgh Spray Equipment defines a stage plainly as a fan, and says more fans mean more volume and pressure, recommending at least a 3 or 4 stage unit for regular use and calling 4-stage the minimum for latex. The Wood Whisperer sets a lower bar, putting 3-stage at $600–$900 and calling it the sweet spot and the minimum for latex, with 2-stage systems at $300–$400 offering "minimal improvement over 1-stage." Both agree clear waterborne finishes are within reach of lower-stage machines. Neither is a controlled test.
Here's why the count misleads anyway. The Earlex 5700 is a 2-stage turbine making 2.2 PSI at 42 CFM, per Lee Valley. The Fuji Semi-PRO 2 is also a 2-stage turbine, and Fuji and Woodcraft both put it at 5.0 PSI. Two machines, same stage count, more than double the pressure. The Fuji draws 1400 watts and 11.5 amps to do it, against 450 watts for the handhelds. The Earlex 6700 is 3-stage at 7.5 PSI.
So "get at least a 2-stage" tells you almost nothing across brands. PSI does.
The twins at the bottom of the ladder
Put the HomeRight Super Finish Max and the Earlex 3700 side by side on paper and each maker's own published specs line up: 450 watts, the same 1.5/2.0/4.0mm tip set with the 2.0mm installed, a 40 oz cup, a 1" to 12" pattern range, three patterns, two air caps, a 2-year warranty. Wagner SprayTech sells the Earlex at $100.00. HomeRight lists its own unit at $79.99, and WoodArtSupply has it at $57.00, marked 8% off $62.00. Wagner owns the Earlex brand. No source confirms they're the same product off the same line, so I'll leave the specs on the table and let you draw your own conclusion. Worth noting the cup capacity is given as 40 oz by HomeRight and 39 oz by WoodArtSupply.
The wrinkle: Wagner rates the 3700 as "ideal" for urethanes, varnishes, stains, sealers and water-based lacquer. That's the machine whose smallest available tip is 1.5mm.
The thinning argument you'll be caught in the middle of
General Finishes says its water-based products are "ready to spray from the container without additives," conversion varnish excepted. Their retail page allows thinning if you need it: start with 5% water, 10% maximum by volume.
HomeRight's Finish Max instruction manual, on ManualsLib, takes the opposite posture. Its run-out chart gives polyurethane a 20 to 50 second window measured with the included cup, and describes two thinning strategies: minimal thinning at 5–6% for the finest pattern with reduced output, or up to 20% for a finer pattern with more output. That chart is from the Finish Max manual, not confirmed as the Super Finish Max manual, so hold it loosely.
Now the gap that nobody bridges for you. Every sprayer maker here speaks in seconds. Fuji includes a #4 Ford viscosity cup in the Semi-PRO 2 box. Rockler sells the Earlex Ford #4 for $4.99, Wagner lists one at $9.99, and HomeRight's FAQ says its included cup is equivalent to a #4 Ford. But General Finishes publishes viscosity only in centipoise, 350–450 cPs, and gives no Ford seconds figure anywhere in the TDS I read. You end up holding a timing cup with no target to time against. I'm not going to publish a conversion, because I couldn't verify one.
The practical read is simpler than the argument: General Finishes' answer is don't thin it, and if you do, cap it at 10% water.
The tip tax nobody prints on the price sticker
Wagner sells a 1.5mm fluid tip, needle and seal for the HV5500/5700 at $75.00, and a 2.5mm kit at the same $75.00. That's it. There is no 1.3mm option in Wagner's line for that gun. Seventy-five dollars is 21% of the 5700's $360 price, and spending it still doesn't get you to General Finishes' spec.
One source oddity while we're here. Wagner's 2.5mm parts page is titled "2.5 MM" and the body text says 2.0 mm, so read that catalogue with a squint.
Cleanup is a design question, not a stopwatch question
I'd love to give you minutes per gun. Nobody publishes them, and I'm not making them up.
What is documented is what has to come apart. The handhelds put the motor in your hand with a 39–40 oz cup and no hose to flush; HomeRight's FAQ singles out the two air holes on either side of the pick-up tube on the Finish Max as the spot that matters, and notes the Super Finish Max has an easier filter change; HomeRight's product page adds a built-in access door for air filter changes. The Earlex 5700 adds a 1 qt PTFE-coated cup and 15 feet of hose. The 6700 adds a 1 qt aluminum Quick-Lock cup, 25 ft Hyperflex hose, and onboard storage for the gun, hose, spare needles and brushes. The Fuji is a non-bleed M-Model gun on a pressurized 1 qt bottom-feed cup, or a 400cc gravity cup on the 2203G, with a 25 ft hose.
Fuji's own cleaning page says almost all HVLP gun problems trace to a blockage in the pressure tube or a simple cleaning issue, and prescribes cleaning after every session. Marc Spagnuolo, spraying General Finishes High Performance through an Earlex HV6900, describes a gentler working practice: he doesn't clean the gun during the day with waterborne, only overnight, and the skinned-over tip pops off with a fingernail. General Finishes says soap and water immediately, or their Brush & Gun Cleaner.
Where $600 actually lands
The budget ceiling in this piece falls in an awkward spot. Within $100 to $600, the Fuji Semi-PRO 2 at $569 is the only machine here that ships at General Finishes' specified tip size. The Earlex 6700 also meets it, and costs $50 more than the ceiling allows.
One last thing worth taping inside a cabinet door. General Finishes' two documents disagree with each other: the April 2019 TDS recommends 3–4 total coats, while the current retail page says 2–3 and no more than 3. The website is the newer document, so I'd follow it. Their FAQ gives the numbers: gun 6–8" from the surface, held at 90 degrees, 25% overlap for topcoats. Recoat at 2 hours, dry to touch at 30 minutes, full cure at 21 days at 70°F and 50% humidity.
If $100 is the budget, buy the handheld with clear eyes. You'll be spraying at 1.5mm against a 1.1–1.3mm spec.
