MBOGO Report post Posted April 9, 2010 so you can us Acrylics then ? thanks.. I need to talk to someone about actually using an airbrush the thing doesnt come with instructions on using the tool itself adjusting this or that.. what is the piece that looks like a long needle. what exactly is the metal cup for etc etc. You absolutely can, that is what the cova colors are. I've used a lot of liquitex products with great success. The needle is used to control the amount of paint that enters the airstream. The metal cup is used for small amounts of paint or die. There are some airbrush websites that show excersizes and instructions, then get some stuff togeather and do some practicing. Have some fun with it.
