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. In February of 2002 she released the book, The Ultimate Airbrush Handbook. In this book she teaches the basics of airbrush art, airbrush types and how to set up an airbrush shop. Continue to practice with shapes until you are able to perfectly render airbrushed shapes. Once you have the ability to render the shapes, you can move on to rendering shapes in different textures. This means that you should work on creating shapes with thin lines and shapes with thick lines. This will help you to learn more how to use the airbrush to render broad designs as well as fine detail. The prep work that you do will be determined by what type of surface you will be airbrushing. 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. 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. Should these parts become dented or damaged in anyway you should replace them immediately. Windex is useful when cleaner your airbrush between color changes while using your airbrush. Never soak or leave your airbrush exposed to Windex for any real length of time. You should not have to take your airbrush apart every night to clean it, it is alright to only do a complete break down and cleaning once a month. This makes this type of paint the choice for airbrushing art onto your model cars or airplanes. This is also the choice for airbrushing t-shirts as well. 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.
