I worked with pro-classic water borne today. It is a beast to work with. I like the 415 tip. I put a little floetral in the paint before I spray. 415, move a little quicker. Keep a mohair 3/16 nap roller with you. Pro-classic sometimes sags. A smaller tip works ok but the room fogs up a little too much. Also wear your resperator!!!! That stuff is brutal on your lungs.
