The Iwata LPH400 LVX ( orange air cap ) is more of their all around gun especially in the 1.4 Fluid Nozzle , I have a 3 LPH400's in the 1.4 with the LV4 silver air cap for Clearing only , the Orange air cap for most metallic's & clears , and the Purple air cap for those mean silvers and pearl's , and works beautiful for Kandies !
I shoot the purple air car gun with 12-14 psi,
the orange cap gun with 14 psi , and my silver capped gun with 20 psi
all these settings are with the trigger fully pulled with 5 turns out from closed on the material knob and the fan all the out with a 1/4 turn in .

I also have an Iwata W-400 1.4 ( compliant ) with the tulip fluid nozzle & silver air cap that works well for primers , single stages , solid base coats , and clears .
Use them all day long every day for the past 4 years and have served me well
