Since the artist can attach the cup to the bottom of the airbrush the colors can be changed quickly by using different cups prefilled with the colors needed. Airbrush art also uses airbrushes with a side feed. The side feed has a cup that mounts on the side. Since the side feed can be rotated the artist can airbrush either horizontal or vertical. Airbrush art on the nails is not for the beginner just getting started in airbrushing. The work area is very small and the artist has to have mastered the techniques involved with airbrushing. One main problem that beginners face is over spraying. Over spraying is when the artist sprays outside of the area in which they are trying to spray. The workshops offered cover airbrush t-shirt art, murals on steel introduction, achieving photorealism, pinup art, pin striping and much more on airbrush art. The pricing for AirBrush Action's workshops runs $150 for a one day class and $575 for the four day classes. This is a small price to pay to learn hands on with experts such as Cross-Eyed, Javier Soto, Jonathan Pantaleon and Craig Fraser. Another great way if you are doing this at home is to allow the design to dry then turn the shirt inside out and throw it into the dryer for about 40 to 45 minutes on the highest heat setting. After this your design will hold up to laundering. If you use a paint that does not require heat setting then you should still set the design. Make several copies of the design since you will be cutting on them. Also the airbrush paint will get them wet and they can start to tear. You will need to keep the original design so that you can refer back to it. After you have made copies of your traced design start cutting out the areas that you need to cut out. Airbrush Art Paints When doing airbrush art there are many types of paints that you can use. The type of paint that you use will depend on what you are airbrushing. Some paints can only be used on certain surfaces and are not safe to use on other surfaces. So make sure the paint you are using is safe for the surface you will be putting your airbrush art onto.
