ppg k38. medium coats, 20 minutes flash time between, 2-3 coats. shop temp is roughly 70ish degrees always (during winter). sits overnight, knock the surface down with 180 and let sit another day to allow solvent to escape. finish blocking with 180, re-prime. let sit overnight, knock the surface with 320 then i let it sit like that until im ready for final block/paint, usually a few days minimum since i work on my personal stuff whenever i have free time. no issues with sand scratches, feather edges or anything else. just faint ghost spots where the welds are. if the panels were not blocked and buffed you probably wouldn't even notice, but on a cut and buffed panel it stands out to me
