Help me please, I am attempting to spray a coffee table top (3' x 6') with Enduro Var II Satin using a Fugi 4 stage and am getting really small (less than 1/36" diameter) but totally aggravating volcano type random peaks.

Finishing Room temp 70 degrees
No dust
Relative humidity = 35%
Fugi 4 stage Platinum - 1.0 tip & 1.3 same problem
Viscosity = 16 seconds

I have shot a ridiculous number of test panels varying the fluid amount from the gun without consistent success.

I have also tried 3mil thickness down to relatively light (think almost leather)

I just bought some GF Extender but have not yet tried it.

Any suggestions, words of wisdom, etc?
