Advantages of Using a Spray Gun for Painting Cars

Best Spray Gun For Painting Cars

  • Greater Productivity

Using a brush to paint your car would be torture. Using a spray gun, on the other hand, will save you time and will give better results. The paint sprayer is connected to a large paint container, and you won’t need to stop to get more paint every 20 minutes.

  • Versatility

A spray gun is a multi-purpose tool as it can be used to paint different types of surfaces. It is suitable for iron, aluminum, wood, stucco, brick, etc.

With such a device you can cover up everything from a bump to a crack. That’s why a spray gun is more practical than any brush or roller.

  • Nice finish

The best advantage of a spray gun is the fact that the thickness of the paint coat can be adjusted. This way you will have the most perfect finish.

Disadvantages of Using a Spray Gun for Painting Cars

  • Price

If you are not sure that you are going to use the spray gun twice, then you may find it a slightly expensive purchase. Still, when you have decided to buy such a thing and not just go to a professional (of course, if you are not one already), it means that you plan to use it many times and not only once. In this case, the price should not be a problem, as you can easily find a spray gun that will be worth the investment.

  • Damages to your car

If you are not a professional, painting your car with a paint gun can get a bit tricky. This is not necessarily the case, but when no proper training course was taken, one could easily cause damages to her or his car or garage. If you are not a professional, look for the best automotive paint gun for beginners.

  • Clean-up

This process is always the most annoying part. It takes too much time and is not at all fun.

Types of Spray Guns

Spray painting is not difficult. We realize there are so many different types of paint sprayers you can choose from, and each one has something to offer. By all means, check out our reviews on all of them. Now let’s look at the different types of spray guns you need to know.

  • Pressure-Feed Guns

We start with this one, although it is not made or used anymore. There just are too many other efficient sprayers that have replaced this model. However, knowledge is power, so we wanted to tell you a few words about it as well.

Pressure feed guns create fluid pressure by using an external source such as a pressure tank. A hose links the external sources to the system. Large industries used to love using pressure-feed guns for they could apply vast amounts of paints regularly.

Pressure-feed guns have served the purpose for a certain period, but modern models showed up and sadly this type is not as efficient or quickly as them.

  • Siphon-Feed Spray Guns

This spray-type has a traditional design, and the cup is on the bottom. The siphon-feed spray gun uses compressed air pressure to draw the paint up from the container through the feed tube. As you probably realize, this type of spray gun requires a lot of energy to deliver the color.

Siphon-feet spray guns are known to be cheaper than most gun types. However, they don’t work well with high viscosity fluids. This is the case with all spray guns, actually. They tend to work better with low viscosity fluids such as dyes, stains, and lacquers. When the fluid viscosity is higher, the application is not that smooth and flawless you would like it to be.

  • Gravity-feed Spray Guns

Their design is fascinating and different. The paint cup is located at the top of the arm. Gravitational force and increased pressure are what make the fluid come down. This type of spray gun offers reduced waste and improved application. This is due to the higher demand that makes the atomization of liquid better.

Unlike siphon-feed spray guns, this type of spray gun is more compatible with high viscosity fluids. Better coating and reduced overspray are just some of the results this spray gun has to offer.

  • Specialized Spray Guns

Some specialized spray guns use other spray painting technologies.

  • HPLV Spray Guns

They use low pressure and not only deliver a significant amount of fluids but also do it in no time with less waste. You can apply several paint coatings to the surface in a short time. The spray is soft and comfortable due to the HPLV turbines, which generate air pressure at a low velocity.

For this reason, the paint does not blast the surface but covers it gently. The reduced paint wastage and little overspray are the two main advantages of this system.

  • LVLP Spray Guns

LVLP spray guns atomize the paint at low pressure, using a low volume of air. They are turbine-driven units that are perfect for small areas where little patterns are required. With this type of sprayer, you won’t even care about what are air compressors.

  • Reduced Pressure (RP) Spray Guns

These are an excellent alternative to HPLV automotive spray guns. Reduced pressure spray guns offer great coating results and higher transfer efficiency than HVLPs. Smaller compressors can work pretty fine with this type of spray gun. RP guns, however, create less mess than HVLPs.

  • Airless Spray Guns

These spray guns reduce the paint loss and provide 70% transfer efficiency. Multistage pumps are installed in the unit to generate pressure. This significant pressure atomizes the paint. The size of the nozzle the pant comes out from, and the pressure plays a vital role in the final finish. Airless spray guns are super useful, especially when it comes to heavy coats and large surfaces.

Factors to Consider When Choosing a Spray Gun for Painting Cars

  • Quality

Spray Gun For Painting Car ReviewsYour car deserves to look outstanding, and if you use a low-quality sprayer, this is impossible. To find the best automotive spray gun, you need to look for a high-quality one that will give you a smooth finish and satisfying results. That’s why it is essential to make sure that the brand of your paint sprayer is well-reputed. It does not matter if you look for the airless paint sprayer reviews or for an excellent latex sprayer, this factor is essential.

  • Type of paint sprayer

Depending on what exactly you want to do, you need to choose the right sprayer type. Every type comes with its advantages and disadvantages. Most professional painters prefer to have one sprayer of each type. However, HVLP sprayers tend to perform better than other models when it comes to painting cars.

  • Nozzles

The nozzle of the gun is one of the simplest and most significant parts of a spray gun. Various vents can be placed on one spray gun. However, many units come with just one nozzle, and usually, it is the one that you don’t need.

Our team recommends that you look for a gun sprayer that comes with a couple of nozzles. The size of the end is usually between 1.0mm and 2.2mm. If you are going to spray more heavy material, you will need a more significant ending.

If you plan to use thinner materials like metallic, single-stage pants and pearl finishers, a nozzle that is around 1.2mm should be okay. On the other hand, if you require to use primers, for example, you will need a nozzle in the 1.8mm range.

It is a good thing that you can buy nozzles separately, and they are not so expensive.

  • Air compressors

Knowing how to choose an air compressor is crucial. You need a device that is able to keep up with your gun. Maintaining the right pressure is vital if you want an exceptional finishing, so your air compressor needs to produce enough air regularly.

PSI and CFM (pounds per square inch and cubic feet per minute) are the two specifications that are essential. People rate paint guns by the number of CFM they need at a certain PSI.

The advice that we would give you is to find an air compressor that produces 1.5 times the CFM that the spray gun requires at a given pressure. This way you will make sure that you won’t have to stop working and wait for your air compressor to restore strength.

You will be pleased to learn that some HVLPs include a motor that produces the air pressure that your spray gun requires. Such complete spray systems are perfect if you don’t already have an air compressor or you just don’t want to buy one. However, if you do want to buy one, always look for the best air compressor for painting.

  • Cost

It is one thing to start a car painting business and a whole other to look for a paint sprayer that you are going to use for one car only. Paint sprayers can cost from $100 to $500 and more. You should choose a unit that fits your budget and plans.

Keep in mind, though, that sprayers that are too cheap are also poor-quality ones. With such a unit you will definitely not have an exceptional finish, and the sprayer is likely to break after the first usage.

  • Reviews and recommendations

Always look for a spray gun that has good suggestions and never forget to read the automotive paint gun reviews.

5 Tricks and Tips to Paint your Car with a Paint Sprayer

Tricks and Tips to Paint your Car with a Paint Sprayer

  • Clean your work area thoroughly! We would recommend avoiding painting under a tree or other object/item that could drop contaminants onto your car.
  • It is essential to strip away the old paint. Circular motions are something you could do using your sanding supplies. Also, make sure that you will remember to cover all the little corners. We suggest getting down to the bare metal.
  • Mask up all the areas that you don’t want to be painted- windows, headlights, windshields, everything! You could use newspaper or plastic sheeting.
  • You need to plan carefully. To achieve a good cover you might need to do 3-4 coats of paint, and you should not rush things! Leave every part to dry out properly!
  • Buffing your paint after the final coat is something you should not forget to do. Knowing how to buff out a car properly is super important. Once you start buffing, it’s best if you do it in circles. Don’t stay in one position for too long as the topcoat could burn.
