@Verdatum - Ah, I didn't know you were at Otakon! You are the person who actually inspired me to use PAX since you seemed to be the only person on the forums who was talking about it. Because of your mention, I dug deeper and decided that it was the way to go, and it worked out perfectly.
As for sensitive skin, my husband did have a slight problem with the paint. I'm not sure if it was the paint itself or the remover, but he has very very sensitive skin, and it left some red irritated spots on his skin for a few hours after we washed it off. They went away very quickly though.
