Three Major Types Of Devilbiss Finishline Guns

Types Of Devilbiss Finishline GunsThere are so many names under this Devilbiss Finishline series. Hence, we would make it as simple as possible for you by categorizing these spray guns based on their most distinctive utilities.

So, in this criterion, there are mainly three types of guns, namely the gravity feed, pressure feed and primer guns.

That means, the first two types of spray guns have their own atomization sucked on gravity and pressure respectively, while the last gun is specifically used for misting primer before applying another paint coat on.

Regarding the gravity fed guns, they are designed in a super portable way with only a single air supply hose, not even a second one for fluid pressure. Also, they are inexpensive and comparatively easy to clean up.

As for the pressure feed guns, they do have more regulation of fluid and pressure in/out with two split flows. They will also come in handy if you’re working with sticky substances since they have higher pressure.

Last one, like we’ve just mentioned, the primer spray guns are used on rugged surfaces such as wood or bare metal to create a smooth and even surface before sprinkling the main layer of paint on.

Best Devilbiss Finishline Products

Now moving on to this section, we’ll dissect three products in details, give them a small comparison and point out their pros and cons.

1. Devilbiss Finishline 4 FLG-670

Devilbiss Finishline 4 FLG-670Editor Rating:

This 4FLG-670 HVLP gravity feed spray gun is arguably the worthiest and most sought-after paint gun on the market.

Aside from featuring the most advanced technology of atomization, it also comes with an air regulator, a twenty-ounce (approximately 591 milliliters) cup capacity, a stainless steel needle and tip for use with various fluid properties, even water-based ones.

The three tips are made for different usage:

  • 1.8 mm to spray epoxy primer
  • 1.5 mm to spray base colors
  • 1.3 mm to spray urethane clear coat

Every part of the gun is very easy for any adjustments, and if built right, it can lay out a precise flow onto the surface.

Actually if you’ve missed some small parts, it can still atomize somehow right. But don’t! In fact, the manual has detailed the instructions very carefully, thus make sure to give it a nice little breakdown before diving into your job.

Another plus point of this 4FLG-670 is that it gives off much less overspray than other counterparts, preventing your money from turning into worthless residues! You can always adjust the stretching width by swiping the fan underneath the gun.

With a correct air pressure plus a perfect flow adjustment, it should pan out a great finish result for your auto paint sessions.

Long story short, this spray gun is definitely the one for beginners and seasoned professionals on spraying base coats or primers.

2. Devilbiss FLG671 FinishLine Waterborne

Devilbiss FLG671 FinishLine WaterborneEditor Rating:

Sharing some similar properties of the last spray guns such as the stainless steel components, enhanced technology of atomization and multiple fluid tips, this FLG671 Finishline nevertheless differs in its waterborne usage.

It means the gun is mainly constructed to work smoothly on tricky water-based finishes such as acrylic, latex or Nexa Aquabase.

That said, it does work effectively on top coats and light primers as well.

Also, the cup is built out of acetal – which provides itself considerable strength and low friction. That, in a combination with an adjustable valve with air gauge and the fluid nozzle, would produce soft uniform spray patterns during the process.

However, due to such strength, the tool consumes quite a large amount of air. Thus, make sure you’ve got a more than decent air compressor to satisfy its appetite, a 13PSM at 23 PSI mark would be recommended.

It’s also easy to clean. Only by rinsing the gun under some lukewarm water, and that’s it. Your spray gun is all set to be used for the next project.

Pros

  • Comes with three nozzle tips
  • Quick and easy clean up
  • Long-term reliability
  • No leaks or streaks
  • Anodized finish
  • Good budget

Cons

  • Consumes a lot of air

3. FINISHLINE Primer DEV-FLG678

FINISHLINE Primer DEV-FLG678Editor Rating:

The last buddy that we are about to introduce you is the Finishline Primer DEV-FLG678.

As its name might suggest, this automotive spray gun is particularly designed for spraying primer. You would have two tips in the box, the small tip for epoxy primer and the bigger one for high-built polyester primer.

Like we’ve mentioned earlier, a primer is a layer of paint applied on to the surface to make it even, to enhance corrosion resistance and to increase paint adhesion.

Adopting the advanced technology of HVLP (high volume low pressure), the process that brings about atomization would prove to be an extremely effective transfer, spreading soft and uniform spray patterns over the surface.

This spray gun also brings the users a pleasant experience with lightweight and ergonomic handle, making automotive painting just as effortless as ever.

Pros

  • Lightweight
  • Can be used for home DIY projects
  • Easy handling & great maneuverability
  • Ergonomic handle

Cons

  • Still a bit pricey
