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 Flat Jet Caps offer a flat spray trajectory making them idea for application on objects as well as sealing with varnish. Both can be adjusted to a vertical or horizontal output and are ideal for use with Montana VARNISHES and CRACKLE sprays, or for use in calligraphy related artwork. The Medium has an average spray width 2.4" to 3.19" and the Wide 4.02" to 5.51".
