spray paiting a car - help

hey fellas let me give you the scoop.

i have an old beat up ford f-150 and its paint is falling off and there is some rust. i would like to sand the rust off and spray paint the car for kicks and giggles.

can you tell me the names of some good spray paint and where i can get it? i dont want to spend too much but i do want it to be decent.
