The only problem is that the paint Paulo used wasn’t water soluble, or easily removed. In fact, what he’d applied all over his body was paint intended for ballistic missiles and nuclear submarines. Paulo had done this stunt before but was forced to use a different paint when what he’d successfully used before wasn’t available at the store.
There is some concern over the toxicity of the paint, although he has shown no symptoms. He’s been forced to sleep in a room covered in plastic, and was only successful in getting most of the paint off of his skin after a day long scrubbing session by friends and neighbors.
