i painted my car for about $150.turned out very well IMO and others for a hour or 2 of work.

Just head to Finishmasters**AutoColor** in lawrenceville or chamblee tucker off 85.
have them Mix up the paint for ya for prolly $70ish per quart and then get a gallon of clear with harnder for $60ish depending on company *my SMART clear was 66 and some change$

if the car is primerd,you need to either sand it with 320g and go back over it with 600g..or like somebody said wetsand it with probably 600g also.

then just go to town..I have a DIY on here from when i did mine.
