Painting A Mask

[🪦 TallDarkandDisfigured ●]

Well, I loev Halloween! I found some liquid latex on clearance at the local store. It was in the Halloween Makeup section.
So if I wanna spray this through my airbrush, how would I mix it? I read 1 part latex to 3 parts paint. But what about thinning it to spray? I\'ve heard of using windex is this true? Any other ideas of what to use??

Thanks again!
