AirBrush Action offers their Airbrush Getaway Workshops that run from a one day class to four day classes and are located in Las Vegas, Nevada. The workshops offered cover airbrush t-shirt art, murals on steel introduction, achieving photorealism, pinup art, pin striping and much more on airbrush art. The less air pressure means that you can use slower movements when airbrushing. The bottom feed is where the cup is mounted to the bottom of the airbrush and the paint is brought up via a siphon tube. It is for this reason that the bottom feed is also referred to as a siphon feed. 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. If you do create your own stencils for airbrushing your automobile do not use paper to create your stencils. Automobiles need lots of paint and this will damage paper stencils rather quickly. So stick with plastic or vinyl material for your stencils. A great cheap plastic to use for stencils is thin plastic folders. Books for Beginners to Advanced on Airbrush Art When looking to learn on your own about airbrush art then reading is one area where you can gain a wealth of information to help you learn more. There a lot of great books out there that will help you from the beginner level of experience all the way through to the expert level. These can be picked up rather cheaply from the store in the office supply section or hit the back to school supplies. You will need an exacto knife to cut your design out. Depending on the size of your stencil you can probably create more than one stencil from this plastic folder. If you purchase the see through folders then you can use these for stencils even if you are limited to tracing your design onto the plastic folder prior to cutting it into a stencil for your airbrush art. Kent Lind will show you how to create cool caricatures in this approximately 70 minute video titled, How to Airbrush Caricatures.
