If this should be come damaged then you could have serious problems with your airbrush. Don't worry though it is not hard to replace these parts should there be any damage. Your airbrush will have a handle on which you can hold onto the airbrush with. 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.
