pump up the pressure on that iwata and increase your fan.. give your self a solid pattern about 8 or 10 inches from the tip of gun that is 8-10 inches wide.. the iwatas look a little tricky and the noise makes the pressure seem wierd.. then over reduce your metalics on the last 2 coats with a hotter reducer.. this will help the metalics lay out even.. my iwata made me so mad when i first got it but its just a different animal.. i love it now.. also for your clear just take the fan down about an inch to tighten it up and lay the gun about 6 or 7 inches from the panel.. should be smooth as glass..
