I think they go by size?? I don't normally ask 'how much' In fact, I try to have that work taken care of by the vehicle owner before I get it. It saves me time, and them money!! Last I checked it was around $1,200-$1,500 to do a complete car.
I don't think they offer the primer option. I usually end up doing it myself, but I think I'm gonna start insisting on having everything e-coated from now on. For the most part, anymore, my job is done when the metal work is complete. I've been a painter for nearly 18 years, and though I still enjoy custom painting, I'm completely obsessed with metalshaping. High quality custom painting takes an overwhelming amount of time!!! I've done so many paint jobs, it takes something pretty cool to peak my interest anymore.
