To do it right you will need several gallons of quality automotive paint, lots of prep materials and a really lot of time. They are not cheap for a reason. It takes time to prep the surface properly, mask off the areas you dont want painted and apply several coats of paint. Then once its dry, masking again and spraying on the trim on different colors trying to maintain balance side to side. Do you really have the time and patiences? It can be done by a DIYer but you have to figure out if you really have the expertise to pull it off? Cost? Thats another factor. Figure two to three thousand dollars in materials alone.
