I paint and transport models all the time. And paint costumes and Halloween for party goers. I find silky smooth fabrics are kinder to body paint both classic and airbrush than textures like towels. It is very hot in the spring, summer and even fall months.
I do suggest fixing the body art with fixing spray for added durability. Some do use hairspray but it can react with various body paints and become sticky and even make the paint gooey. For extra umph use a fixing spray under and over makeup.
Do have a touch kit on hand - I do but rarely use it, Especially once you've covered the body paint with fixing spray - forget it it is what it is. Usually my kit just stays dumped on the ground. If your concerned paint as much as possible and paint the remainder on site.
