From what I've learned about it, you have to consider the primer/sealer color. Then, I would use a paint panel sample to determine how many base coats to use to get complete coverage. Also, it takes a final coat to make sure the metallics are distributed correctly or you will see blotches in the finish. 3 coats of clear, flashed out between each coat at a minimum.
I saw 2 gallons as a suggestion. I used 3 but I did the roof and the undercarriage as well.
Just my experience.
Cheers!!
Final Result.
