Airbrushing metallic paint onto plastic is a tricky process that requires the right tools and materials. One of the most common issues people encounter is clogging, which can be caused by metallic flecks getting stuck inside the airbrush. To avoid this, it is recommended to use a gloss primer and the right type of paint, such as Vallejo Model Air Metallics, which has good coverage and can be easily cleaned with water. Other recommended paints include Polly Scale, Tamiya, and Model Master, which are known to be as easy to use as their non-metallic counterparts. It is also important to clean your airbrush thoroughly after each use, especially when switching between metallic and non-metallic paints, to avoid any unwanted sparkly bits in your next paint job.

What You'll Learn
Metallic paint brands: Vallejo vs. TurboDork
When it comes to metallic paint brands, Vallejo and TurboDork are two popular options, each with its own unique characteristics and performance.
Vallejo metallic paints are known for their high quality and ease of use. The Vallejo Model Air Metallics line is particularly renowned for its excellent coverage and easy cleanup with just water. This makes it a convenient and efficient choice for airbrushing projects. Vallejo offers a range of metallic colours, including gold and grey, that can be used directly in airbrushes without the need for thinning. Their Metal Color range is also specifically designed for airbrushing and provides a consistent shine when used with a gloss primer. Additionally, Vallejo's Air range is safe to use in airbrushes and will not cause any damage to the equipment.
On the other hand, TurboDork metallic paints offer a unique selection of colours with a focus on metallics beyond the typical silvers and golds. They have an extensive range of metallic colours, including a sought-after metallic purple shade. TurboDork paints are known for their large pigments, which create a smooth metallic surface with individual sparkles and shine. While the paints provide good coverage and sparkle, they can be challenging to clean from airbrushes due to clogging. It is recommended to use the right kind of cleaner for their Liquid Metal alcohol-based paints.
In terms of consistency, TurboDork paints tend to be thinner, which can make them easier to work with when airbrushing. They require fewer coats compared to Vallejo, with one to three coats typically providing good coverage and sparkle. TurboDork paints are commonly used on plastic, resin, or metal models, but they can also be applied to other surfaces like canvas and wood.
When choosing between Vallejo and TurboDork metallic paints, it's important to consider your specific needs and preferences. Vallejo is a reliable option known for its ease of use, cleanup, and wide range of metallic colours. TurboDork, on the other hand, stands out for its unique colour offerings and smooth metallic finish, but may require additional care during cleanup due to clogging issues.
By understanding the characteristics of each brand, you can make an informed decision based on your project requirements, desired finish, and ease of maintenance.

Airbrush types: single-action vs. double-action
When it comes to airbrushing, you have the option of using either a single-action or a double-action airbrush. So, what's the difference, and which one should you choose?
A single-action airbrush is one where the trigger only operates one action – the air. When you press the trigger on a single-action airbrush, the airflow is turned on, and a pre-set amount of fluid will be sprayed. The amount of fluid can be controlled by turning either a fluid tip or cone on external mix airbrushes, or a preset knob or ring on the handle of internal mix airbrushes. This can be done with your other hand during spraying, or you may need to pause your work to adjust the setting. This method is less convenient than the instant control offered by a double-action airbrush. Single-action airbrushes are, however, useful for applications where you want long runs at a steady pre-set spray pattern, and the pre-set prevents you from overshooting.
A double-action airbrush, on the other hand, allows you to control the air and paint flow independently of one another. So, you can spray a larger amount of paint at lower air pressure or a smaller quantity of paint at high pressure. This gives you much more control over your work. Double-action airbrushes also allow for infinitely variable paint flow and pressure control. The only real downside is that they are slightly more complex to use, with a slightly higher learning curve.
Both types of airbrushes have their advantages and can be used to achieve excellent results. However, if you want more control over your paint and air flow, a double-action airbrush is the way to go. Just remember that it's important to clean your airbrush thoroughly, especially when using metallic paints, to avoid clogging and ensure your next paint job is fleck-free.

Cleaning your airbrush
To ensure a great airbrushing experience, it is important to clean your airbrush regularly and at the end of each spray session. Here is a comprehensive guide on cleaning your airbrush:
Quick Paint Flush
Perform a quick paint flush between colour changes. Use the Iwata Washing Brush with Medea Airbrush Cleaner or an appropriate alternative. Wipe the cup out and spray the cleaner or water through the airbrush until it sprays clear. Spray into a Spray Out Pot or paper towel.
End of Spray Session Clean
At the end of each spray session, it is important to clean your airbrush thoroughly. Soak the nozzle, nozzle cap, and needle cap in Medea Airbrush Cleaner to help break up dried paint. Do not soak or immerse your entire airbrush in any liquid. Use a clean brush to scrub off any remaining paint residue.
Deep Clean
For a deep clean, you may need to strip your airbrush down to its component pieces. Soak the parts overnight in a concentrated cleaning solution. This will help remove any stubborn paint residue and prevent clogging.
Additional Tips
- Always clean your airbrush before the paint dries to avoid any paint build-up.
- When removing and reinserting the nozzle, use a nozzle wrench or a small spanner, being careful not to over-tighten to avoid breakage.
- Clean your airbrush's colour cup before changing colours, especially when switching between colours on opposite sides of the colour wheel, like yellow and violet.
- If you are using acrylic paints, you can run glass cleaner or water through the airbrush, followed by a thinner or denatured alcohol to remove any residue.
By following these steps and adapting them to your specific airbrush model, you can ensure that your airbrush remains in optimal condition and provides a seamless painting experience.

Priming minis
There are several ways to prime miniatures, including using a spray can, a brush, or an airbrush. Using an airbrush to prime miniatures can result in an even and smooth coat of primer, which can improve the quality of the final paint job. It also offers more control and versatility than other methods. However, it requires a dedicated space with proper ventilation and is not as beginner-friendly as other methods.
To prime minis with an airbrush, it is recommended to use a well-ventilated area protected from overspray. This can be as simple as a cardboard box near an open window or a dedicated airbrush spray booth with an exhaust fan. It is also important to wear a respirator mask or a COVID mask to protect yourself from inhaling any particles.
When using an airbrush, it is crucial to thin the primer to the proper consistency, similar to the viscosity of whole milk. This can be achieved by adding a flow improver or airbrush thinner to the primer. To test the consistency, use the back handle of a paintbrush to drag some primer up the side of a cup. If a small droplet forms and slides down, the consistency is correct. If the primer is too thick or too thin, adjust by thinning the primer with water or adjusting the air pressure on your airbrush.
The ideal air pressure for priming miniatures with an airbrush is around 20-30 PSI. When applying the primer, use short, even strokes up and down or back and forth. Dual-action triggers are the most common type of airbrush for miniature painting, allowing for airflow when pressed down and paint flow when pulled back. To apply the primer, keep the air on and pulse the paint as you spray across the miniature.

Using a gloss primer
Firstly, choose a suitable primer for plastic surfaces. Look for a solvent-based primer that is specifically designed for use on plastic models or kits. A gloss finish primer will provide the desired shine and form a good base for the metallic paint. Always test the primer on a small area of the plastic first to ensure compatibility and check the manufacturer's instructions for proper application techniques.
When applying the gloss primer, follow the recommended spraying distance and technique advised by the manufacturer. Typically, spraying at a distance of at least 25 cm from the surface with an even back-and-forth motion is advised. Allow the primer to dry completely according to the product instructions before proceeding to the next step.
After priming, you can move on to the metallic paint application. Select a high-quality metallic paint suitable for airbrushing, such as the widely recommended Vallejo Metal Color range or Testors enamels. Ensure your airbrush is clean and follow the paint manufacturer's instructions for thinning the paint to the appropriate consistency for airbrushing.
When airbrushing the metallic paint, consider the desired effect. Multiple thin coats can build up a smooth and even metallic finish. Play around with different techniques, such as mist coats versus wet coats, to achieve the desired result. Remember to clean your airbrush thoroughly after each use to prevent clogging and ensure smooth performance for future projects.
Finally, consider the benefits of a clear coat finish. If the item will be handled frequently, a clear coat can provide added protection and durability. However, keep in mind that a clear coat may alter the final appearance, making it look too perfect or "show car-ish." Depending on the desired level of realism, you may opt to buff the finish with fine steel wool to add a subtle scratched texture.
