The prep work to the surface will ensure that the paint sticks to the surface and that nothing is interfering with the airbrushed design. For airbrushing t-shirts, sweatshirts, denim and other natural fibers you first need to wash the material. By washing the material you will remove any loose fibers. Some magazines are in print and with the access of the internet there are airbrush art magazine online as well. Whether you are reading and learning more about airbrushing in a printed magazine or an online magazine you are sure to gain knowledge of the airbrush art industry. Airbrush art can be seen in magazines that are designed to teach techniques geared toward airbrushing in a more broad-spectrum. Magazines such as Hot Rod, Airbrush Action, AutoGraphics, Easy Rider, Mini-Truckin have featured Shanteau's airbrush art in their publications. These of course are just the tip of the iceberg when it comes to publications that have featured her work. Shanteau does not just create brilliant airbrush art, she also teaches others how to create the same high quality airbrush art that she herself creates. 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. But as long as your project is made from the above material you can use water soluble acrylics for your airbrush art designs. Depending on which brand of acrylic paint that you go with, you may need to thin it down so that it flows freely through the airbrush. Also some acrylic paints require that they be heat set if used on clothing. Any damage to your needle can cause very bad paint spray patterns. It is important to keep your needle from getting bend and either straightening the needle or replacing the needle. The air cap and head assembly are on the front of your airbrush and they cover the tip of the needle. The purpose of these parts is to control atomization of the paint spray.
