A spray gun includes a panel having a number of openings for engaging with a number of elements which are coupled to the panel by a number of studs. The elements may be disengaged from the panel by braking the studs for allowing the elements to be assembled into the spray gun. The elements are secured to the panel for allowing the elements and the panel to be easily displayed. The elements may be easily seen by the user and may be easily assembled together by the users themselves.
