The 350 is an external mix, single action air brush. Air and paint mix outside the air brush, creating a larger, coarser dot pattern and providing a heavier spray volume. The 350 is superb for base coating, stenciling, stipling, touch up projects, etc. An excellent choice for beginning students, hobbyists, ceramists, and automotive painters. This model sprays high viscosity materials such as ceramic glazes and stains, and hobby enamels with ease. It is also effectively used with properly reduced acrylics, inks, dyes, watercolors, acrylic lacquers, and enamels. The 350-3 Kit includes the model 350-3 medium nozzle airbrush, with attachable jar, vinyl airhose, additional jar with cover, 1/4 oz. color cup, propel regulator, propel can, wrench for needle assembly and instruction manual. The 350-1 H Kit contains airbrush with heavy head, 2 jars, wrench, and instruction manual.
