Many showcard men find that an ordinary fine spray atomizer will do very good work, and some even attach an atomizer to a home made air pressure tank, which is fed from a hand or foot pump.
Any method that will add novelty to the appearance of a showcard is very good, especially at the important seasons of the year.
In doing air brush work however, or spatter work, it is very necessary to first procure the regular air brush colors. Ordinary homemade mixtures will drip and ruin your work. The regular air brush colors have in their composition a dryer which causes the color to dry immediately, and also a binder which prevents the color from being rubbed off. Air brush colors are very reasonably priced, and can be secured in a great range of shades and colors.
If the student has difficulty in procuring these materials, he should write to the Educational Department of the Associated Advertising Clubs as suggested in previous lessons.
