Exactly. As an sfx mua watching this I was thinking...why paint a silicone hand with alcohol paints? With as much silicone as it took to make that, it'd be better to paint it the correct way with thinned down (with naphtha) intrinsically pigmented silicone. The color will never budge. I'm guessing this is just a demo of the pigmentation/quality of the palette though :)
Which colours were you using in this palette? I'm using the Jordan FX palette which seems to be a replica of the Skin Illustrator, but slightly less pigmented when activated with alcohol. The activator works quite well though
