Think of paint 'maps' on a model as the skin taken off and made flat. On this particular model.. map4 contains all the parts you see in yellow and all the parts you see in grey are on other maps (dds bitmaps) taken from the grey paint to temporarily fill the holes in
A gloss finish on this would look smashing..not too glossy but more than it is at the moment. Not sure if anything can be done about this though as the degree of shine is set in the model and the corresponding specular.dds maps that go with it. I'm not trying to re-invent the wheel.. just do a cheap 'knock off' The same can be said for the EC130 paints. The model and maps reflect an uber shiny 'civvie' helicopter and while the VIP fits this well.. the RN grey is too shiny.. but ok at a distance On the first 'yellow' version I did.. I took the yellow from the Virtavia RAF paint which, with how the Virtavia model is setup, looks fine on that. On the UH60.. the same colour looked like it had been taken from one of Graham Norton's shirts!
The colour above was taken off one of the many RAF rescue Sea King pictures I downloaded last night from an area which appeared to be in natural light (not in shade or direct sunlight) and looks a whole pile better believe me I tried to search for the correct RGB of the yellow and the best I came up with was from a model paint supplier which had a touch too much red in it and Simmers Paintshop (which also gives RGB's) only had training/research yellow 
Notwithstanding the fact I can't put the wording where I want it to go without it either covering or being covered by aircraft part labels (open here, don't touch this e t c).. I think this will end up being a lot more 'what if' than it would otherwise have been
I may have a go at RAE/A&AEE at some point.. if I don't get bored first and move onto something else ATB
