Disclosed is a portable painting and drying apparatus for facilitating painting and drying of wooden blocks such as cabinet doors. The portable painting and drying apparatuses are formed using various components such as bases, poles (e.g., metallic poles and wooden dowels), joints (e.g., single and double-pole joints), a spinner, hangers, a spray gun holder, a hitch clip, a hanger organizer, a hitch clip holder, a rail connector, a rubber washer, or a thumb screw. The painting apparatus is used by a painter for painting all surfaces of a cabinet door at the same time. Upon completion of painting of the cabinet door, the painted cabinet door is transferred to the drying apparatus for drying.
