It depends on a lot of things, but if you have more than one paint job on there, I would strip it to bare metal and start from there. I also would pull out all glass, handles, bumpers, trim, roll bar, etc. Before these get reinstalled I repaint or detail these as needed. If the metal dash needs painted, then all of the switches, radio, gauges, etc. get pulled out. Everything gets primed and sanded 2 to 3 times and then sealer, color, and clear is sprayed. Another thing is the inside of the jeep. Lots of times we shoot the inside with bedliner, either black or color matched to the exterior. It's not hard to spend 50 to 100 hours on a jeep paint job if you want it to look like it came off of the showroom floor. You can figure anywhere from $2500 to $4500 labor depending on the condition of the body.
For me to go to the paint store and buy primer, sealer, color, clearcoat, tape, sandpaper, etc, etc. to paint one vehicle, I spend approximately $1200-$1500. Maroon is one of the more expensive colors to buy (more than bright red usually). Add pearl in the color for a "sparkle" look and it can go up even more. I use the good PPG paint, not the inexpensive line.
A good paint job is like anything else, you get what you pay for.
