Over spray is a real problem because of the fine aerosol mist these produce. It requires at least 5 cans for total body coverage. These are opaque, but apply thin with a brush, and dry quick. I haven't tried them with airbrush yet, but they should work well. With a little thinning, 2-3 ozs.
Most primary colors are available, along with glitter metallic.
Warnings are on the label against using red, pink or orange in eye areas. These may be my new favorites, even though they cost more. The red stains a little on skin, but cleans off easy. It does stay tacky for awhile , so you may want to apply setting powder. So far I've only used the yellow, which seems to go on thin, and doesn't seem as flexible as the MagicColor.
