Many use enamel paints for its durability, and glossy finish. But this begs the question as to whether or not enamel paint can be used in an airbrush? Enamel paints have been around for many years and the technology has progressed substantially.
However, given the viscosity of the product, and the elements that make up the “Paint”. It’s no wonder this question arises as often as it does.
As you likely already know, paint must be thinned to the right consistency before running it through an airbrush. Otherwise you are likely to end up with clogs, inconsistent spray patterns and so forth….

Below we will go into further detail as to why it is so important that you clean your airbrush thoroughly after you’ve finished painting. Especially when using enamel paints.
But first, let’s go into detail as to why enamel paints must be thinned to the correct viscosity before use in an airbrush!
Why Enamel Paint Must Be Thinned Before Application
As a refresher, Enamel paint is essentially a term that means: Hard & Glossy finish. Simply put, enamels are designed to achieve a durable, shiny finish once cured. In order to achieve such outcomes. Enamels are produced using specific components / elements. These elements can cause an airbrush troubles if the mixture has not been thinned to the right consistency.
The viscosity of the enamel paint to begin with may vary depending on the manufacturer you
The reason for thinning enamel is so you achieve a smooth and consistent spray of paint on your part. In most cases you want to start by thinning your enamel paint to the consistency of milk.
Thinning to a consistency of milk will provide you with a good starting point. However, you may need to thin the enamel more or less depending on the pattern you’re looking for, and the way your airbrush acts.
It is recommended that you test your enamel paint on a similar spare part before applying it to your final piece.

I recommend you avoid using this method when working with enamels.
Though you likely can getaway using this method when working with water based paints, but Enamels require thorough thinning of the paint, and by simply dumping both your thinner, along with the paint into the airbrush paint cup, and backflushing it.

Now, depending on the paints available to be used in an airbrush, some can be more forgiving than others when left to dry in an airbrush. But enamels are not one of those. You see, enamel paints are designed to be durable.
What do you think would be the outcome if a durable (Hard / Tough) paint was left to cure inside your airbrush? Odds are it will be very difficult to remove. Now, of course any paint that has dried inside an airbrush will be difficult to remove (Clean out). But an enamel paint that it’s specifically engineered for durability…
Lets just say, cured enamel inside an airbrush could essentially mean retirement for that airbrush. Obviously this depends on the severity of the situation. But why let it go that far.
