Reed you werent steering me away from doing it. Ive just read up quite a bit on doing this with spray paint as well and it seems more often than not, the person doing it is highly unsatisfyed, you gotta think its extremely tough to get all the grease and such outta that bay in order to get a good coat of primer down, then sand that and wash it, then another coat of primer, then scuff that then wash, then paint, scuff, paint, wet sand, wash, clear, wet sand, clear. if you plan to have the car or the pay painted down the road, people have numerous times regretted it because of the extra amount of effort that has to go into the prep work in order for the "professional paint job" to stick and look decent.
not to be the bear of bad news but continue researching this.
