All there is to paint body color with the panels off is a 1/2" border on the edges of the hood, doors and trunk and the fender and quarter lips inside the front and rear compartment. You can do all that with a single spray can you buy the color of your car from Duplicolor. Certainly not worth the days it takes to disassemble and reassemble the whole body...at least to me. I can see it if your restoring a 69 Camaro where theres a lot to paint besides the outside. If you just want to, or feel better doing it, its not that its a bad thing though. Its like repainting your whole house because you scratched the door.
