After finishing the primer coats, I found some defects/pin holes that I wanted to address so I went back with fairing compound in a few places.
I should have followed up with a primer coat in these areas, not so much for paint adhesion, but to reduce the number of paint coats I'd need to obscure the green fairing compound. But, I was out of primer, and my order for more primer and paint just got delayed a week.
In any case, I moved on to painting with the 2-part Epifanes Polyurethane. I also only have one 750ml can of this as I'm waiting on the same delayed shipment. It seems like 1 can gets me about 2 - 2.5 coats. It's really unfortunate that the paint is delayed, as I was assuming I'd be able to apply the 3rd and maybe 4th final coats without having to sand -- since the recoat window is 48 hours.
I'll try to see if I can obtain the paint locally, but it's not looking good.
But hey, the boat is starting to really look professional now!
