thanks guys, I cant believe the difference in tip size made, I also just slammed on my second coat on the hood with a 3rd coat directly after my second pass, minus the trash it came out slick and no solvent pop or sags at all.
My clear of choice for the type of booth I spray in was PPG Deltron 4000 but have to use the dc4010 now to meet voc regulations, and well I finally tried the dc4010 at $240 for a kit and for the price it doesnt spray any better then the 2.1 so Im gonna stick with the 2.1.
