Primed the interior with SEM self etching primer then sprayed the interior with JetFlex water soluable aircraft interior paint and a 3M accuspray paint gun. I mixed the paint 5:1 using distilled water. Some areas came out smooth and some didn't. The air adjustment screw was out about 1/2 turn and the trigger adjustment screw was out 3 turns. Air gun pressure was inadvertantly at 120 psi then reduced to 90 psi.
