PAX Paint

FX Warehouse carries an exclusive line of Surpranant PAX Paint just for Trekker Makeup.
PAX Paint is an Ahesive paint that will stay on all day, but needs a special remover to take it off.
You can either sponge or brush it on, or dilute it 50/50 with distilled water and airbrush it. It will be sticky after applying (it's an adhesive) so you'll need to powder over it to get rid of the tack.
Purchase by the complete kit, which has 6 colors including 3 Klingon colors, 2 Cardassian and an Andorian Blue. These makeups are the exact ones used on Star Trek movies. Thom Surpranant was one of the main makeup artists on those shoots.
