Oh my goodness, what a wealth of information. Once I've deciphered all of that stuff about paint specifics, this will be very useful. XD
All joking aside, though, this is very cool, and thank you for posting all of that and answering all those questions--most of my questions were answered earlier in the thread, so I'm not going to bother repeating them. This will be super helpful for a cosplay I want to do later, and I'll definitely look into getting some after I've started officially working on it.
I do have one quick question, though, just to clarify: you said you were able to put makeup on as well, but you did put it on over the PAX, right? I figured you probably did, and it doesn't really make sense otherwise, but I didn't know if it was translucent enough that the makeup showed up through it, or... whatever.
