Boy, that really depends on the system you use.
Most modern paints require you to put down the entire
package in one go- the coats 'melt' into each other for strength.
And the upper coats expect quite a bit of softness to the ones
beneath them.
That said, look at the product data sheet- it'll tell you.
Frankly, given the fast flash times of most paints,
I can seal, basecoat, and clearcoat an entire car in maybe 3 hours-
in fact, if it takes longer, I've had system problems.
I put on a complete coat, refill the gun, then start again.
It flashes as fast- if not faster- than I can work my way around the car.
And I'm a rank amateur- I shoot a car maybe every
couple of years, with a few 'partials' here and there.
Personally, I just like getting it done- it takes longer to
clean everything and mask up than it does to put color on.
fwiw,
