Figures used years ago to paint a car ranged in that 30-35 hour range,figure in jams then body work and materials it adds up. I would guess you would have at least 40-60 hours in refinish time by time you do jams and outside.. Body work figure double that to be on safe side. You are approaching 150 hours easy. If you find a shop say round here the going rate is 48-53 an hour, figure in materials you will have 2-4k easy by time go from primer to clear. My best guess is 10k-15k give or take a few pennies.
