It is very dangerous to become invisible by spraying T− particles onto the body. Any small T+ source like a cigarette bud, a lighter fire, or any hot surface will cause a flow of T− particles away from the body. This high current of charged particles "electrocutes" the person instantly.
Besides, invisibility provided by T− particles is detectable by infra-red and shows up as white washed region of very cold temperature.
Suicidal Assassin you are not.
