My brother decided to try this method after reading countless articles. I have to say it was more pain than it was worth. A can of automotive spray paint works better and leaves less sanding work to get it looking nice. We both gave up and he just drives it around half poished. It was a CRX btw. I cannot imagine the paint someone would go through if it was a car any bigger. I have painted a few cars in my backyard (when I was in HS) and my futile attempts came out better looking than any rustoleum job.
