OK so a bit of update here.
I painted the wing with Model Master Metalizers Aluminum, which is a lacquer paint and then painted Vallejo Model Air OD and NG paints top and bottom. This allows me to chip away the top coats and have paint flaking. Problem is it comes off way too easy. But I am getting the results I was looking for, just a bit too much. Need to do what I want and seal it.
So as mentioned before I'm trying Vallejo's Metal Color lines on the rest of the fuselage in a kind of pre shading style so I can try to chip away at just the panel lines.
We'll see how that all works out.
I built out the two booms and and there is an open section forward of the main gear that looked like it was just waiting for some weight. So after talking to Dale, (Yeah I know, only bad things can come from talking to him), I followed his advice and it worked like a charm. Test fit bird shot into the hole, pour it and some two part epoxy into a mixing cup and after mixing, pour said back into the cavity. I did start this process out by sealing the front of the boom with Tungsten putty. The engine mounts to the boom via a hole in the front of the boom and so I would not block the mount and not let shot run out the tungsten putty filled the hole and leaves room for the mounting of the engine. Mike turned me onto this stuff some time back, though I use it sparingly as it is quite expensive.
Next I started working on the Wright R-2800 engines. The Vallejo Metal Colors paint sets each come with a back card that when opened up give you how to suggestions wo do something. There are four paints in each set and I have picked up all four. The Four are "Engine", "Metallic Panel", "Jet Exhaust", and Aluminum Dope". Here is the how to for the Engine set.
Though it looks pretty slick I did not think it depicted the R-2800 correctly. I must say though, I really like these metals.
From Wikipedia
I started by painting the whole tree Vallejo Gloss Black, which is highly recommended when using the metals. These paints brush on as nicely as they airbrush on. I brush painted the rest of the engine using three paints so far. The exhaust is in burnt Iron, the cylinder heads I used dull aluminum and the ring I used steel. The burnt Iron and steel aren't showing through well as they are dark but it looks pretty good so far ro me. Still have quite a bit to do to it but it's moving.
