DeVilbiss FLG-670 Review Summary:
The DeVilbiss FinishLine FLG-670 is an HVLP gun from the 4 series of paint sprayers. Both straightforward to use and to clean due to the anodized exterior and interior DeVilbiss FLG4 parts — you’re ready to tackle anything from a complete car respray to a fender touch-up.
Falling into the high-volume, low-pressure category means that the DeVilbiss FinishLine 4 delivers a finer finish with very little overspray. This trims down wastage — leaving more paint for other projects that you may have on the go.
Once you dial it in, the DeVilbiss FLG 670 delivers even coverage without the orange peel effect. Furthermore, with a choice of three fluid tips, this gravity-fed gun can handle a whole host of solvent-based mediums.
High-grade stainless steel components make for a durable, long-lasting friendship. Plus, with its air adjusting valve complete with gauge — you will never want to be parted.
DeVilbiss was established in 1888 and is one of the founding fathers of the spray painting industry. Many years of research into their products have helped them develop user-friendly paint guns that are modestly priced.
Features and Benefits of the DeVilbiss FinishLine 4 FLG 670
HVLP High Transfer Efficiency
According to the DeVilbiss FLG4 manual, HVLP (high-volume, low-pressure) delivers maximum transfer efficiency. This means that you end up with more paint on “target” and less wastage.
To get the most out of your HVLP gun — make sure that you don’t use more pressure than is necessary to atomize your chosen paint.
Precision Machined Air Cap and Fluid Nozzles
The DeVilbiss FLG670 features a precision machined air cap and three different sized fluid nozzles — optimizing the desired finish to your project.
The 1.3 mm nozzle is suitable for base coats and clear coats. The 1.5 mm is a solid all-arounder with multiple uses on different materials. Lastly, the 1.8 mm is designed with primers in mind.
Anodized Exterior and Internal Passages
Another nice touch that’s included in the DeVilbiss FLG4 parts breakdown, is the high-quality anodized exterior and internal passages. This leads to a durable, simple to assemble, disassemble and hassle-free cleanup gun.
It’s well known that religiously cleaning your sprayer after use leads to a longer lifespan. What’s more, if your gun isn’t such a chore to clean, you’ll be more inclined to complete this tedious task.
900 cc Aluminium Cup
Unlike other plastic loving models on the market, the DeVilbiss FinishLine FLG4 comes with a durable aluminum 900 cc cup. This means you shouldn’t need to purchase replacements too often.
However, the paint cup cover is plastic. Yet, it’s recyclable and also features a unique drip check to prevent the paint from trickling out of the vent.
The large size of this cup also means fewer interruptions to your spraying — you won’t need to refill the paint quite so frequently.
Air Adjusting Valve With Gauge
The air adjusting valve with gauge allows for greater control and fine regulation of your spray job — meaning you get the results that you anticipated.
The valve reduces dips in pressure to your DeVilbiss FLG4, while the gauge enables you to know the exact pressure — so that you can spray efficiently.
What Users Say About The Devilbiss flg 670
So far in this Devilbiss FinishLine 4 review, you’ve heard all about what I think. But, what do the guys and gals on the painting frontline have to say?
It seems that I’m not the only one impressed with the performance of this spray gun.
Many mention the DeVilbiss FinishLine FLG 4 is a game-changer and makes it so much easier to achieve that pro-look finish. Users also rate its incredible atomization, perfect coverage and pattern.
The only drawback noted was the lack of a filter to prevent debris from spoiling your paintwork. However, this can be easily rectified by purchasing the part separately if so desired.

It still includes the same three fluid tips and a gauged air adjustable valve. It’s also anodized for ease of cleaning. However, as the name suggests, it’s designed for use with water-based materials — base coats, topcoats and light primers.
Furthermore, when it comes to the post-project cleanup — these types of mediums are less hassle to deal with.
- Suitable for water-based mediums, whereas the FLG 4 is for solvent-based.

- Includes an acetal (plastic) cup — as opposed to aluminum of the FinishLine.
This handheld unit features three fluid tips (1.5 mm, 2.0 mm and 4.0 mm) and two spray caps — enabling fine spray and wide spray. Furthermore, with adjustable controls, such as paint flow and spray patterns (horizontal, vertical and round) — you can tailor this gun to your task at hand.
Although, weighing in at 3.3 pounds, it’s double the weight of the DeVilbiss.
- Option of three spray patterns, whereas the FinishLine 4 FLG-670 only accommodates one (horizontal).
- Like the DeVilbiss, the Homeright includes three spray nozzles.
- Features an Inbuilt turbine — no need for a compressor like the DeVilbiss FLG 4.
Featuring a 1.3 mm spray tip, as well as a Pattern and Fluid Control dial for fine-tuning the spray pattern and amount of paint dispensed. All medium components consist of durable stainless steel, plus it incorporates an Easy-Pull trigger to reduce painting fatigue.
- Smaller paint cup (600 cc) than the FinishLine 4 (900 cc).
- Components are stainless steel — like the DeVilbiss.
- Similar price point to the FLG670.
For the automotive enthusiast or expert that wants to achieve quality results — the DeVilbiss FinishLine 4 FLG-670 HVLP spray gun could appeal.
The three different sized fluid tips can grapple with a wide array of materials, from topcoats to heavy-duty primers — along with covering projects of different sizes — such as respraying that classic Cadillac to pimping your latest ride.
It’s large 900 cc paint cup means less downtime for refills, allowing you to complete your project swiftly. And, once you’ve reached the end of your task, the anodized internals paves the way for hassle-free cleaning.
