What to Look for When Buying an Automotive Paint Gun

• Hose Length

Something as simple as the correct hose length can make a world of difference to your overall comfort level when working with a spray gun. Investing in a device with a long hose will help you spray areas that require a ladder since you will be able to access these places without having to carry the paint container. This is especially the case if you happen to be working on a large project with a portable spray gun set on wheels. Some models come with an extension cord so you can take advantage of those extra feet to paint fences and doors.

• Container Size

There are many sizes available from small paint guns to large ones that are better suited for professionals and automotive paint enthusiasts who have a long DIY project ahead of them. Small paint guns are ideal for less time-consuming jobs that require small amounts of paint. They can also be used for touch-ups and for surfaces that require a small spray pattern rather than a large one. If painting the entire body of your car or truck is your goal, then you will most definitely need a handy spray paint gun like the Graco Magnum X7 that comes with a cart and a sizable five-gallon container.

• Adjustable Features

One of the handiest features that you need to look for in any automotive spray gun is the knobs or buttons that allow you to control the paint flow and pattern. The key to a smooth and professional finish is using the right pressure and pattern while working, which is why these individual knobs are important. The more control you have over the spray paint gun, the better. Having a wide range of pattern options and air pressure levels to choose from is better than spending more money on a new gun or two because your first choice did not have this incredibly versatile feature.

• Filter

Some paint guns require the right filter-nozzle combo in order to deliver the kind of texture and finish you see on professionally painted surfaces. Some filters are used for light substances like varnish while others were designed for primers and other heavy-duty industrial and automotive coatings that can lead to clogging issues. Many models have their very own built-in filter that helps take care of this problem.

• Nozzle Size

This is a crucial component that comes in a variety of sizes. You will need a spray paint gun that has the right kind of nozzle for the job you are about to do. Heavy coatings need larger nozzles since they are usually thicker and those include resins and primers. If you use the wrong sized nozzle, then you risk ruining the surface. Buying a device that comes with at least three sizes for different fluid viscosities and applications is the way to go.

• Portability

A portable kit allows you to save both time and energy, especially if it had wheels and an extra storage compartment for all your additional gear. Being able to carry everything with you eliminates the need for constant trips to your garage where you keep all your supplies. Investing in this kind of kit will also come in handy once you start painting your car. Wheeling the portable cart is better than having a stationary container without wheels. Some small spray gun brands also come with a shoulder strap so you can keep your hands free for spraying.

• Gallons Per Minute

DIY projects take both time and effort, so you need a device that allows you to be efficient without having to cut corners in terms of quality. A good spray paint gun will have a high GPM number or Gallons Per Minute. This translates to the amount of paint the device can transfer from the container onto the desired surface in a minute. If you have a big project and want to achieve fast coverage and a flawless finish, then you can choose a design with a high GPM so you can finish your task on time.

Types of Paint Guns: HVLP Vs. LVLP

• HVLP

HVLP paint guns produce low pressure to atomize the paint while releasing it in high volumes. Therefore, the HVLP stands for High Volume- Low Pressure and most of these paint guns run on turbine motors that generate around 100 CFM at a pressure of approximately 3 to 8 PSI. This design leads to a high finish quality and more money saved on paint and other materials. It also consumes more compressed air and has more energy demands when compared to the LVLP spray gun. HLVP spray paint guns are ideal for DIY ventures and for beginners who need a dependable device. High volume means less overspray and more precision in terms of application. HVLP are also approved by the Environmental Protection Agency due to their overspray reduction feature.

• LVLP

The Low Volume -Low-Pressure spray paint gun is very energy efficient and prevents paint from being wasted. Purchasing one of these devices is money well spent and a chance for you to add another great and handy tool to your ever-expanding toolbox. LVLP paint guns can be used for waterborne paints and deliver the best coverage and finish with watered down paints. They are also compatible with many air compressors and require around 10 PSI at the nozzle. Make sure that you purchase a device with higher volume if you plan on working with metallic or highly viscous paints. Inventing in a pricey spray paint gun is always recommended if you are a weekend warrior with plenty of DIY tasks on your to-do list.

Best Automotive Paint Gun FAQ:

Q: What is a paint gun and how does it work?

A:  Paint guns are similar in shape to regular guns but were designed for paint application. They rely on the atomization process that turns fluid paint into small drops. These drops create a fine mist that escapes the gun via a special nozzle. The mist then colors the intended surface. Paint guns come with their own container and have several knobs, a trigger in addition to an air cap and nozzle. They are also equipped with either a turbine, air compressor, or motorized pump depending on their size, type, and model.

Q: Do I use more paint with a sprayer?

A: The amount of paint used depends on the type of sprayer you own. Generally speaking, it is always recommended to buy 20% more paint just to be on the safe side. Touch-ups and double coats are sometimes inevitable. HVLP spray paint guns require more paint compared to other methods like rolling and bushing. Airless paint sprayers typically need double or triple the quantity of paint compared to a roller since they depend on high pressure to atomize fluids. The same applies to sprayers that rely on air compressors.

Q: What PSI should I use to paint a car?

A: Painting any car requires consistent pressure that delivers the same amount of fluid each time. This consistency is achieved with any premium spray paint gun. Therefore, it is recommended to go big in terms of gallon and compressor capacity. In PSI, this means around 90 PSI and around 14-18 CFM or Cubic Feet Per Minute. This can be achieved by purchasing a sizable 60-gallon tank with a 6-horsepower compressor.

Q: Can I use a paint sprayer to apply primer?

A: Yes. The ideal paint sprayer for this specific undercoat is the gravity feed spray gun. Remember to always consult the instruction manual before you begin and make sure to use the right air cap size and nozzle.
