temp paint...

I am wanting to know if there is any kind of paint/primer that might come in a rattle can that will not have to be completely taken off to repaint the car later?

what I am wanting to do is work my way over the car one part at a time. like pulling the front end apart, prepping and doing any body work then shooting a couple of coats of primer and paint then reinstalling the parts. after I get over the whole car I want to basicly sand down the exterior and paint it all at once to make it look consistant.

this is my first attempt at paint and I just want to make sure I don't waist my time with some thing I have to completely redo.
