So keep your airbrush clean with the right cleaners and once a month do a full break down and cleaning. With needles most artist find that the airbrushes coming out of China bend easier than any of the other airbrushes. So look for one that is made elsewhere so that you do not have to keep trying to straighten a bend airbrush. When you begin you need to place a base coat of Opaque White first before you begin your actual airbrush design. Wood surfaces should be sanded prior to doing any airbrush art. Take the time to use sand paper and lightly sand the wood down by hand. If you are doing a mural on a wood floor then use a hand floor sander. To take things to the next level and gain some insight straight from an expert, then enroll in an airbrush art workshop. Airbrush art workshops are offered around the world by many expert artists who will show you up close and personal how to create art like a pro. These workshops range from beginners to advanced classes. 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. Damage to the air cap and head assembly will effect the performance of your airbrush. Thus like the needle you will be unable to create desirable airbrush art. Anything can be a basis for inspiration, especially if you change your scenery and look around your new surroundings with open eyes. Cooped up in a studio too long, then go out to the park and open your eyes to everything that you see. Derive inspiration from various sights around you and incorporate them into one great piece of art. These airbrushes create a large dot pattern. Larger airbrushed areas are better done with the external mix. Since with the larger dot pattern you are able to spray more areas in less time. Airbrushes also come in single and dual action. This refers to how the airbrush functions. With single action only the air is controlled with the trigger.
