After speaking with a few different car painters about spray guns and hardware, we’ve learned that there’s no common type, brand, or even age, really it all comes down to personal preference. Since car painting relies heavily on technique and not how expensive your gun is, even older- model spray guns are commonly used with superb results. Proper maintenance, which includes lubricating and cleaning the moving parts of the gun, is critical if you want a consistent spraying gun that won’t spit and spatter. Competent painters will also rebuild the gun after a certain number of uses. Eastwood.com offers extensive gun cleaning kits that include the brushes and picks needed to tidy up a clogged gun.
