Obviously, I'm the world's worst ceiling painter. I use good paint (Sherwin
Williams), stir it well, apply it with the right equipment (3/8" nap
roller), keep a wet edge, and the ceiling still ends up with roller marks
despite my best efforts to apply an even paint film.

Suggestions?

A nap roller might qualify as the "right equipment", but if you want
to avoid the problem simply buy or rent an airless sprayer. Once
you do a job with one, you'll never go back to a roller. They are
sooo much faster and easier..
