Happy Thanksgiving everyone!
Progress:
I got the lower hull and secondary hulls/symmetrical warp field generator section painted their final color. I had to get the final color applied before I could install the nav lights and glue up the sides, since the nav lights are under one of the mount points for the sides. Also so that I could get the shuttle bat lights installed as the fiber optics have mushroomed ends for lenses so had to be pulled through after painting.
I was going to use Model Master Aluminum Plate Metallizer but: 1) enamel over acrylic just wasn't happening on the blue nacelle grills (the transparent blue is Tamyia acrylic) and 2) I thought the metallizer was way too silver and bright both in person and compared to what's seen on screen. So I went with a new brand - Vallejo Metal Color, "Duraluminum". It's much warmer and more toned down than the Model Master paint.
I couldn't be happier with the results of this paint. It's airbrush ready, It sprayed on very, very smoothly and covered extremely well. The end result is an absolutely amazing shimmer of dark metal - it looks incredibly realistic - I couldn't stop looking at it for 2 days! ...and no buffing or special sealing is required. It's exactly the color this ship needed. The photos just don't do this paint justice. It looks stunning in person.I can't wait to get to the aztecing.


The first coat of this metal over the gloss black blew me away - it blended in with the black and looked like something out of a terminator movie - it presented as a very industrial futuristic metal like nothing I'd seen before. I wish I had thought to take a photo of it after its first coat. I really can't rave enough. I'm definitely going to keep this brand in my back pocket for metal paints.
So anyway, with that done, I got onto getting the lighting finished.
I think the first thing I did was glue that sensor dome in there. I've been waiting to see it against the silver hull. It looks awesome. I didn't get a photo of that, but you can see it in the other photos.
Then I went after the nav lights, then the hull perimeter lights (lit via fiber optic). There are 6 of these on the lower hull. I used the clear inserts that came with the model and glued fiber optic to the back of them to throw light into the clear piece. The result looks good.

I used some 1mm LEDs I picked up at my LHS for the floodlights below the launch bay control room. They fire directly out those openings and man, do they throw some light. They help add some ambient lighting to the outside of the hull.
The openings on the outside will be filled with Micro Krystal Klear a bit later, encasing the LEDs in a lens. With that done I installed the control room I had made earlier.
I wanted the windows to be very see through and since I used the paragraphics detail for the windows, I had very thin window frames to work with. Rather than krystal klear, I cut a window out of thin clear styrene and glued it in place with krystal klear before the control room went in. I'll get some pictures of this and the nav lights, and the other exterior stuff once I get the inside done and turn my attention to touching up the outside of the hull.
It's getting messy in layers inside this hull. I also glued the control board in.


The fiber optics for the shuttle bay lights:
On a side-note, something I should have done differently - the black primer light blocking coat and white reflective coat before any fiber optics went in - spraying over the fiber optics, I think the primer etched into them a bit. It doesn't seem to affect light output at all, but it made them brittle in several spots where the paint got thick. I broke and had to repair one of the cargo bay lights just as it came out of the hull inside - I just cut it off flush with the hull and glued a new fiber optic to the cut end. I used CA so the ends would melt together slightly and not diffuse the light. It seems to have worked, I can't tell the difference between it and the unbroken one on the other side.
A couple of the hull clearance lights:

And I got the LEDs drilled and fiber optics attached for all of the optics on this bottom layer of the hull. The second photo is the shuttle bay lights. I had to use 2 LEDs - there are a total of six 1mm fiber optics and four 0.5mm fiber optics.

Getting all this done allowed me to get the mess of fiber optics and wires sorted and tidy. Well, relatively tidy anyway...
The next layer of fiber optics will be the sides. There are four optics each for the two docking ports and three optics each for the four little thruster/sensor panels. Then the deflector dish, small impulse engines and lights (I gotta do some cutting and fabricating here), paint the landing deck, do some touch-up, and the lower hull should be complete.
