Body and especially paint work is learned by trial and error and $$$.To save yourself alot of the above you should seriously consider taking a course in auto painting.You will save a lot of headaches not to mention $$$$$.In 2 to 3 months i think you could have the understanding and confidence to take on your paint job with the knowledgr to avoid making mistakes.Time and money well invested.Not to mention the hook ups with others interested in painting also,hell,usually you can use your shop time to work on your project with the instructor there to bail you out in a bind.
