Once we had a similar issue when painting the lower hull. The paint seemed 'flat' after application, but one day later it looked a bit like orange skin. We did all according to the manual but finally had no idea what was the cause. Our theory is, that the previous coat was not yet dry enough and the second coat reacted with the first coat and some outgasing happened.
We changed strategy and waited about two days between coats with sanding between coats. No issues since then. I have to say we used two-part paint everywhere.
We did sand the primer with 120 then 240 grit. Between coats of paint we sand with 400 grit.
