They look just like paint from a distance and even up close it's hard to tell. Occasionally, someone will touch the car and discover the truth. Temporary Paint Once again, don't attempt this at home unless you are willing to accept the possibility that the paint might leave a mark on the factory finish. With that in mind, there are two types of paint you can use. Tempera paint and AquaFlow, a special automobile paint from a company in Georgia.
Tempera paint is a good all purpose paint that even kids can work with safely.
It can be applied to the car with regular or foam brushes, and comes off easily with soap and water. The only drawback here is that it will also come off if it rains. Oh well, we are talking temporary here. If you want your masterpiece to last through a rainstorm, you might consider a new automobile paint called AquaFlow. It is designed to be applied to cars with an airbrush, though just about any method of application will do.
