Getting close to priming then painting (after a week or so and some more sanding) my '68 Satellite.

I've seen various opinions on where to start painting and in what order to go in. Some people start in the middle of the roof.

If the car is all together, what order do you go in? I figure I will practice going in order, with the primer, then practice some of the single stage on a spare fender before doing the actual car.
