Rubber Mask Grease is made especially for use directly over latex or foam latex surfaces such as masks, fake wounds, bald caps, or other latex and foam latex appliances. RMG contains castor oil, which coats appliances and the surrounding skin with sufficient oils to allow the latex piece to appear natural and not chalky, as it would appear if you used ordinary creme foundations over latex. In addition, RMG is hyper-pigmented, yeilding great coverage over a wide variety of skin and fake skin surfaces. *Each RMG shade has a matching Graftobian F/X Aire Airbrush shade. HINTS: Use a metal knife and scoop the product out onto a palette. Soften the makeup by working it up on the palette. Seal the appliance first before applying the makeup. Graftobian recommends using Pro Adhesive for this purpose. To create washes of color, add a couple drops of 99% isopropyl alcohol to the rmg on your palette. The wash may be stippled on for dimension and texture with a sponge. (Dont apply this mixture near the eyes due to the alcohol content.) Set the makeup with powder and then seal it with setting spray. Airbrush paint can then be applied over the top.
