Smooth-On Psycho Paint
Psycho Paint® is a versatile and easy-to-use platinum silicone paint base developed to help special effects and prosthetic artisans, doll makers, etc. easily create painted-on colour effects for their platinum silicone creations. It is a two component translucent clear platinum-cure silicone that is used to make a base for colour pigmenting. Once the desired colour is attained, Psycho Paint® is thinned with a solvent. Thin layers of paint can be then be applied to a model's surface (made of Dragon Skin®, Ecoflex® or other platinum silicone) using an airbrush.
In addition to painting the exterior of a cast piece, you can apply Psycho Paint® to the inside of a platinum silicone or urethane rubber mould and then cast platinum silicone behind it. It can also be applied by brushing.
