These paints are ready to use and will save you from having to deal with thinners and such. Save those types of paints for when you have gained yourself some experience with airbrush art. Stick to ready to use black paint from Golden Airbrush Colors because it really does not matter how the paint looks at this point. In a single action airbrush the trigger controls the air flow. In a dual action airbrush the trigger controls both the air flow and the paint flow. Beginners should really take the time to practice on how the trigger works so that they can perfect their ability to airbrush. Your airbrush will have a back lever as well that acts to shut off the air flow and paint flow when the trigger is released. When you begin you need to place a base coat of Opaque White first before you begin your actual airbrush design. Wood surfaces should be sanded prior to doing any airbrush art. 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. The type of feed you choose will also depend on what you are doing as well as what you are comfortable working with. The gravity feed is a top mount cup that uses gravity to pull the paint down into the airbrush. This feed is great for airbrush art designs that call for fine detail as the gravity feed uses less air pressure. Thus the interior of your home can be your canvas for your airbrush art. Whether you want bold or subtle the choice is yours when you airbrush. You do not have to be limited with just your walls inside your home. Everything in your home can prove to be an area to show off your creative side. Airbrush art can go on your cabinets, doors, toilet seats and so much more.
