@sukimba: I didn't have any problems with sweating or overheating in it, but keep in mind that I'm always cold and don't really sweat at all (plus we were inside all day in air conditioning). Sweat is mostly water though, so the paint does not rub off with sweat (my husband who was also wearing PAX "tattoos" sweats a lot, and the paint didn't budge). Basically though, the only thing that will make it come off is the PAX adhesive remover.
I don't know if you will have problems with your skin breathing through the paint if you do tend to sweat and/or overheat easily. You may want to test the paint on a large part of your body and wear it around for a couple of hours to see if it's uncomfortable.
