Since it is a track car...(and I suggest you try ChumpCar) I'd just prep it as best you can and let Maacco paint it. They have complete paint jobs for $259. You cannot beat that.
Not around here they don't. Walk in any shop like that around here and they are like sharks that won't do anything but the top of the line.
Even if you prep it? What's the top of the line run? $500? I should have my dad come help ya. He painted my brothers 79 5.0 a nice gloss black in our driveway. Car still shiny today 15 years later.
