Looks like as Jack stated I was free handing the airbrushing and most have had to much overspary which really blurred the lines. On the engine cowls I decided to tape the demarcation using a little elevation in the tape as to not create a hard demarc and the results are what I expected. You can clearly see the two colors. Another lesson to add to my "what not to do list". Since beauty is the eye of the beholder I might not just leave it this way.
For what its worth other kits that I have built from Italeri have had better quality then this one, V-22 Osprey. I could a list of issue on another thread.
This what I like about this forum I usually get good responses in record time. Thanks ALL.
