Buyers’ Guide


What should be the container size of an auto paint gun?

This is dependent on your needs and the requirements of the task that you are doing. If you are working on something that will need tons of paint, then you should consider a large container. That will ensure that you do not have to refill the spray gun as often. It will also let you work on the project with more focus and you will not lose momentum and will complete the work faster. With that being said, if you are working on a small scale task, then it is worth going for a small container size as it will save you cost. Generally, getting a spray gun with a larger container can be beneficial as you will not have to get a large container later on.  

What adjustable features should you look for in an auto paint gun?

If you are looking to get a spray gun, you should consider one that has adjustable features. These features include things such as adjustable paint flow. That can ensure that you have more control over the spray gun and it will not over-spray. This can give you a better end result and make your projects have a professional look. Another feature to look for is the adjustable pattern control. This can allow you to have more versatility as you can switch between various patterns of paint and spray from any angle. Some paint guns also let you adjust the pressure of the paint gun. This ensures that the paint gun has less bounce back and is good for smaller areas. 

What is an ideal nozzle size for an auto paint gun?

Nozzle sizes determine how fast the paint gun will spray the paint. This is something that depends on your necessities. While painting surfaces such as walls or fences, going for a larger nozzle size will be useful as you will get more coverage. Also, most large nozzle guns can even use thick paints. That can save you a lot of time and effort because you will not have to thin the paint beforehand. But sometimes a large nozzle can mean that you do not get even coverage. You would have to recoat the surface to get the best results in that case. Whereas, a small nozzle means that you get less coverage but get a more even coat. This can take more time but will ensure quality paint.  

How is hose length significant in an auto paint gun?

If you want to work on large scale projects, having a hose that is long in length will be a good thing. This is because a long hose gives you more accessibility and lets you move around more freely. It will also help you reach tricky places. On the other hand, if you are working on a small scale project, then you might not need a long hose. We would suggest that you invest in a long hose paint gun so that you can work comfortably. Another great feature that some paint guns include is the flexible hose. A flexible hose will allow you to spray the surface from various angles allowing you to get a better end result.
