A 1974 Duster - My 2nd one, 41 years later!

OK, my car is 100% in white epoxy, wet sanded to 800...smooth as smooth can be. It will be coming off the lift and set on jack stand towards the front of my shop. The doors will be coming off so I can paint the jambs when shooting the car in Green. The question is... Do I tape off and paint the fender tops, door tops, around the windows, and cowl in black now before the the Green and doors coming off??? Or should I pull the doors and paint it all in Green and then hang the doors back on and then paint the black areas??? Seems like it would be easier to paint the black Now before shooting the Green. It would be a lot less to tape off when shooting the Green. What do you think?
