So the choice is yours as to whether or not you want the handle on or off of your airbrush while you are creating airbrush art. Pay special attention to the threads on your airbrush. The threads are located on the head assembly and where the air hose connects to your airbrush. If these threads should ever become cross-threaded then you could end up with an air leak. By acquiring the skills needed to do micro airbrushing the artist can capture more detail in their airbrush art on the model car. Imagine being able to create realistic eyes on a dragon you just airbrushed onto the hood of a small model car? When a person looks strongly at your artwork on the hood of the model car they can really see the capacity of the skills that you have as an airbrush artist. 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. 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. You don't want to mar the wood only remove any rough areas. If the wood has been waxed or has a gloss coat then sanding this will remove this and allow for the paint to stick to the surface. If you have experience then start where you know and go forward advancing through airbrush art techniques. Workshops can cover a wide variety of different styles and techniques of airbrush art. Makeup artists that practice airbrush art for makeup sometimes will offer workshops in their salons to teach the art of airbrush makeup. Thus airbrush art was being experimented with on vehicles at this point. The way we use airbrushing now to create art surly has come along way from the primitive methods used by our ancestors and even our parents. Now a days we can see airbrush art almost everywhere on almost every type of surface. The only limits now a days with airbrush art rests in the limits of the individual artist.
