What kind of paint can I use on my car?

[everlastes]

I want to paint some flowers on my car free hand. it's a 94' corsica with 264000+ miles on it and is on its last few breaths of life. I hit a pole the other day and scratched some of the paint essentially totaling the car. I want to paint some flowers on it to make it more fun for me to look at. what kind of paint could i use to paint (with a paintbrush and stencil) on my car that won't come off with rain or bleach with sun? I'm also on a budget, so as cheap as possible.
