Montana Cans feature a cap system with a variety of interchangeable caps that allow artists to customize spray width on the same spray can to achieve different effects for different projects. Cap nozzle sizes range from ultra-thin, for detailed work, to extra-fat for covering large surface areas.

The leveled spray caps feature an easy-to-understand identification system based on both shape and color, and result in a varying spray output ranging from very skinny to super fat lines. The three skinny caps have an indented cap head and a black dot nozzle. The three fat caps have a rounded head, and pink or orange dot nozzle. Within both groups of skinny and fat caps, they range from narrow to wide spray widths based on the cap color - the green darkening as the spray width increases.

Green Level 1 Ultra Skinny Cap allows for an average spray width of .15" to .6".

Green Level 2 Fine Skinny Cap can produce lines from .25" to 1" and is great for fine work and fine fading.
