Colors can be mixed to create your own unique color for your artwork. When putting airbrush art onto an automotive use acrylic enamels. These are not only cheap but they will not clog up your airbrush like lacquers. Also make sure that you buy mixed colors and avoid any tinting colors, since they do not contain any driers in them. The trigger will control the air and the amount of paint that comes out is determined by the needle adjustment on the back of the airbrush handle. Dual action is when the trigger on the airbrush controls both the air and paint. The trigger is pressed down for the air and back for the paint. Now when it comes to the feed on the airbrush there are three types of feeds that you can choose from. No matter what material you go with make sure that you remember to cut out your areas slowly. By taking your time you can make sure that everything matches up the way it should. If you are doing a stencil for say a dog then you would want to take your time and make sure that the eyes were the same size, the nostrils were cut out shaped the way they should be and so on. It is in these small areas that a lot of artist miss the chance to really define the details because they are unable to fully create the detailed area. Micro airbrushing is needed to really capture the details of these small areas. Micro airbrushing is also a valuable skill for an airbrush artist if they airbrush small model cars. Artists have been airbrushing a variety of surfaces for years now. The images they create are just a vast as the surfaces that they are airbrushing them on. This is why airbrush art fits for just about everyone around. Classic paintings can be airbrushed onto canvas to give for great wall art. With airbrushing the paint goes on to the canvas more evenly than if it had been hand painted. The wild psychedelic artwork that was popular with that era were done thanks to the use of airbrushing. Tie dyed looks and large hippy flowers and even the peace signs were making their way onto vehicles during this era. Airbrushing the artwork on took a lot of time out of painting the vehicles over doing the designs by hand.
