Spraying ceiling all the way down to the base
 

This is a rental property, I am painting an enitire modular home, 2100 square feet with stucco cathedral ceilings. I was thinking of spraying the ceilings and continuing down over the crown molding, doors, walls and down to the base molding.
I like the look of crown, doors, case and base with semi-gloss.

Should I spray first with a flat, then go back and paint the moldings separately? or spray the same color/finish and then spray the wall a separate color for contrast?

Any thoughts would be appreciated.

Not a great idea to be spraying inside a finshed home. There will be over spray every where.
The only time I see spray used on the inside is before the trim, flooring and doors go in.

Ever sprayed before?
You can screw up in seconds what would take many hours to fix.
Think about it.

I should have mentioned. Home is empty and there is no flooring.
