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
REDUCER IS DRR1185
