After a long search for the right type of paint and the best way to apply the paint for us. We went with the Wagner 3500 sprayer and with Sherwin Williams Everlast paint. Both we bought from Lowe's. After a bit of a learning curve with painting roof, I was able to dial it in a get a good finish on the rest of the paint.
Good luck on your paint project!
