...learning is the key here, I'd love some feedback from you all, on both my canopy faux pas, as well as the shading techniques you like.
Hey Gunny, your helo is looking great. I wish I had one. I built up Revell's HH-53C and would love to have a USMC Echo too. I just don't know if I have the space...or the cash!
Anyway, I wanted to share my two cents about painting modern USN and USMC grey schemes. By no means am I a pro, but I tried something on a Super Hornet I built and was happy with the way it came out. It's called "black-basing". There are a ton of "how-to" videos on the web about it, but here's how I did it in a nutshell.
As far as what I did, it was pretty basic. First, I primed everything in black. (Duh.) Then, I sprayed the lower color, the lighter LGG, first. I thinned the MM enamels to about 50/50 with some laquer thinner. I sprayed it at a low pressure, about 15 psi, with my airbrush pretty close to the surface. The paint was sprayed in a random pattern and the goal was inconsistent coverage. I shot one panel at a time, in a completely random, almost "squiggly" pattern. If I wanted a darker, dirtier, more mottled look, then the base color was sprayed more haphazardly and the coverage was more inconsistent. If I wanted a cleaner "greyer" look, then I made sure the coverage was more consistent and complete. The upper DGG surfaces were approached in the same fashion. Once I was happy with the overall coverage, then I sprayed some DGG "splotches" on the lower lower surfaces, and conversely, some LGG splotches on the upper surafaces. I didn't do any "lightening" of the base colors. It was all about coverage. Besides those two greys, I picked some random greys and shot them in random places and with random coverage to give that beat-up "touched-up" look to my airframe.
I avoided pre-shading the panel lines because, to my eye, I didn't see that "pattern" in reference pictures. If I had to do it again (and I will), I think I'll use thinner paint and a more random spraying to give the modern airframes a more "operational" look. Maybe even go back with a lightened base color and spray more splotches into the center area of some panels. The great thing that I noticed about this techinique is that, if you have to go back and fix any boo-boos, and/or do any spot touch-ups, all of that will add to the overall effect of the paint.
I hope this helps. Good luck with the rest of your build. I'm looking forward to seeing this monster all wrapped up.
Cheers!
