Paasche a name brand in airbrushes and airbrush accessories offers up an exceptional video titled PAASCHE Airbrushing with the VL. This video is offered on DVD and runs about 30 minutes. This video deals with teaching the beginner all about double action airbrushes. In spite of the fact that the video is geared towards the Paasche VL airbrush, the information taught in this video will work for any double action airbrush on the market. Once you understand the different options that are available and the benefits of each option you will be better able to determine which airbrush you need for which projects. For the paint you have an internal mix or an external mix. The internal mix is when the air and the paint both mix inside of the airbrush. Leather needs to be wiped down with rubbing alcohol prior to doing any airbrushing. This will remove the oil that is on the leather. The oil will prevent the paint from sticking to the surface. Make sure that all the leather has been wiped down and that the alcohol has dried before beginning. When you begin you need to place a base coat of Opaque White first before you begin your actual airbrush design. Now that you are ready to begin airbrushing the tattoo on, you need to take your time and be careful of what you are doing. There are no rooms for mistakes with airbrushing on a person's skin. So take your time to ensure you don't make a mistake on a person's body with the airbrush paint. While experienced artists understand this, again a beginner may not. One way is that you can use stencils or masks to airbrush your artwork on to your project. The other way is that you can freehand the design onto your project without the use of stencils or masks. Most stencils and masks that you purchase are reusable. The stencils are made from different material depending on what the stencil will be used for. During the 1930s airbrush increased when advertisement agencies jumped on the bandwagon to create advertisement of new products. Soon airbrushing would be used to paint Pin-Up girls on to the American planes during WWII. This is where airbrushing started showing up in the more modern world in the form of art.
