You should be able to do the wing in about 8 passes maximum. A pass should not take you more than 10-15 seconds.
Double check your mix and aperture.
Be sure to release the trigger completely at the end of each pass.
What p.s.i. are you supplying the gun? What type of gun, i.e., gravity fed, suction, HVLP, airless, are you using?

Hi Mike thanks for your response:-
I knew it was a technique problem - what I'm doing is holding the trigger down like an impatient teenager and pretending to be Leonardo Da Vinci. I didn't really want to be running all the way up and down the length of the panel like a robot - I was trying to produce an even surface by looking at the "density" of the colour as it fell on the surface. (Do you see what I mean?) My technique was a bit more like trying to make even swirls of polish on the hood of your car - like those slick dudes on the Discovery Channel! (Confused?)
Anyway I've got a compressor - air line - filter - old fashioned pipe in a cup spray gun. I think the gun is made by Sunex - I'll post a photograph if it helps. You can adjust "round" on the top dial and the lower dial regulates the fluid flow out of the cup. The amount of air is regulated on the regulator at the compressor. I've set it up to be 70PSI when I'm holding the trigger down.
When the weather is good again I'll rub down the panel and try the set up with a bit more flow... at least now I've got a better idea of how long the job should take - thanks!
Another thing that may be important:-
I have noticed that when I sprayed the panel with spray filler (with an aerosol) I got a nice smooth as a baby's butt finish. However, after spraying the colour coat I got a finely pitted - rough as a badger's arse finish...
