The 1.4mm tip is perfect for base coats and metallic as the droplet size allows the particles to self-orient to eliminate streaking and mottling. For spraying a whole car, a 1.3mm tip is recommended. Here’s what Kevin Tetz and Eastwood recommends for the Concourse HVLP gun.įor spraying clear coats on small parts and projects, we recommend a 1.2mm tip. Usually the instructions that come with the gun will have a handy spray gun tip size chart too. Oftentimes, the paint or primer will come with recommendations as to how to spray it. As a general rule of thumb, thicker material like high-build primers use a bigger opening, while thinner liquids use a smaller tip. Eastwood carries a selection of popular sizes for the guns we sell. Most guns have the option of several different-sized spray tip openings with a matching needle for each one. Choosing the proper HVLP spray gun tip size will give you the right combination of speed, efficiency, results and ease of clean-up. But most important to the quality of the job you are doing is using a gun with the right size fluid tip and needle for paint, primer or whatever else you are spraying. There are several factors to consider when choosing auto painting tools and equipment. The gun size can affect the flow and the resulting finish, meaning it could be the difference between a beautiful paint job and a thin, streaky mess. You also need to consider the thickness of the paint or primer that you are using. Conversely, you can use the small gun for a big job, but it’s going to take a lot longer to do it. You can still use the big gun for a small project, but it is going to be more wasteful and messy.
What you are painting is important to a certain extent, but more important is what you are painting with.įor example, if you are painting a small panel or a motorcycle gas tank, you should use a gun with a smaller spray pattern than if you are painting the side of a van. When spraying paint with a compressed air spray gun – whether gravity feed or siphon feed, conventional or High Volume Low Pressure (HVLP) – it’s important to have the gun set up properly for the job.
