When someone offers you a cheap paint job, run away. As Tony pointed out above, the prep is over 90% of a paint job. Cheap paint jobs minimize prep Then there's materials. Just the paint, reducer, primer, etc from a good paint company like DuPont, RM, PPG, etc, for a single stage urethane paint job, will cost you $400 or more. For base coat clear coat add $200 more to paint cost.
