I just finished putting up new drywall and sprayed a white primer on the ceiling - 2 coats. The ceiling looks good and I'm trying to decide if I really need to paint the ceiling now or can I just leave the primer as it is?

Primer isn't meant to last to exposure. Also its not washable like paint is should something spray like a soda can.

Hi, fbwright!

Just using primer as a finish coat can be fine. However, is there going to be a lot of moisture generated in the room that has been painted, please?

Thanks!

Paint the ceiling since you already have the room prepped for spraying. It will be a kick in the butt later on if you have to paint it.

If you don't paint it make sure there is good ventalation or dehumidifier in there. I agree. It's a pain but it is already set up. Just paint it with a glossy paint
