    I am encountering a few random solvent pops spraying PPG DCU2021 clear.
    Gun is Eastwood Concours. current gun setup is:
    1.2 setup in gun ( have 1.2, 1.4, 1.8 kits )
    Fan is 1.25 turns out
    Fluid is 1.5 turns out
    air pressure is 28 – 29 PSI at the gun, trigger pulled
    spraying 8-9″ above surface.
    mix of clear is 4:1 :1 dcx61 is hardner, DT1185 is reduer
    booth is 85 to 90 degrees. Base coat had no pop issues, but may be a bit too dry,
    felt like 220 grit when you run your hand over it. base is DBU9700 MIXED AT 1 : 1.5
