The talc powder is to be applied to the tattoo after it has dried. The powder helps to keep the tattoo from fading. The 70 percent alcohol is to clean the airbrush gun and glass bottles with after you are done. Airbrushed art used to create tattoos will last for 7 days on the norm. Now if you have extremely oily skin it could start to fade in a couple of days. If you find that you are not getting inspiration no matter where you are looking then it is definitely time you stepped away from the airbrush art for awhile. Take a few hours to do something other than airbrushing and let your mind go for awhile. You will be surprised how quickly your inspiration comes back and creative juices start flowing when you just take a breather. This kit includes a 4 outlet air manifold, 4 single action ABA airbrushes, 12 glass airbrush bottles, 4 air hoses, 10 60ml of airbrush art tattoo inks in white, blue, red, yellow, violet, fuchsia, green, fluorescent green, fluorescent yellow and fluorescent blue and 1 120ml of black airbrush tattoo ink. The use of talc powder after the design has dried will help to keep oil from building back up and thus still ruining the airbrushed tattoo. Nails should be clean and buffed prior to beginning. Buffing the nails will give for a rougher surface for the paint to cling onto. Prior to actually airbrushing the nails, a base coat should be applied. 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. The cost for this art is expensive and you can cut your costs down by learning how to do it yourself. Also by doing it yourself you have more of a say in how it will turn out. As you can see airbrush art can fit for anyone's tastes and needs. With airbrush art you can go extreme with fantasy art or murals of realistic scenery.
