What kind of paint is best for car windows that is also easy to remove?

I want to paint the back window of a truck. It must be temporary and, if done right, harmless. And by temporary, I mean only on for a couple of hours. Please keep in mind it's very likely the paint will be exposed to precipitation at some point.





So, is TEMPURA best or ACRYLIC?





This is URGENT!!!

don't use either of those, i would go for a water based latex paint and thin it down as much as possible, you should be able to peel it off with a little hot soapy water and some elbow greaseWhat kind of paint is best for car windows that is also easy to remove?
Just use white shoe polish. I don't think I'd be comfortable using paint.
