I am buying my first airbrush gun and I need a little help on what to get. I need help on the type of gun and if I should use paste or the other. Thanks

by paste are you referring to the colors??? Definitely don't use paste coloring or gel coloring you need to get "airbrush colors" specifically!! You don't wanna ruin your airbrush especially since they can be quite costly! I would reccomend getting airbrush cleaning solution as well and then hole yourself up in a room and have a ball......airbrushes are soooooo much fun!
