well if you dont know how much your going to plan on spending you better plan on spending 2 times as much as it should cost and expeshly if you dont know what your doing. have you ever painted before? and well if you dont know where to get the paint at then im starting to think that you have no clue what your going to do, it might be better to have some one that knows what their doing, do it, but you i can answer your questions, if you are planing on buying paint you can run up to your local wal-mart and buy like 2 cans then you deffentaly need a clear coat so it dosent fade or chip or some thing, but it will probly take you a can if you want to put enoph coats on it.
