A sprayout card will let you know how many coats for full coverage. Certain colors can mean more or less coats. Also if I buy more than a gallon I mix them together in a 3.5 gallon metal pail to make sure they are one color (I’ve seen slight color variations when buying 1 gallon and extra qt or 2 from same jobber).
Adding jambs, door frames, underneath deck lid, roof, etc need to be considered.
I always like to have a couple pints of base left over for future.

The best advise so far, in my opinion. I always intermix like described after a long run on the shaker. Then I pour off a pint of base to save before any paint work begins.

Speaking of Nason, I once had to paint a 71 'Cuda front bumper (Lemon twist yellow) with Nason. It took 17 coats to hide the gray primer. I have not sprayed Nason base since.
