Part 1 of the construction of the Polar Lights Enterprise is the shuttlecraft bay and cargo deck. I knew the old Enterprise hangar deck well - in fact while in high school I built a TOS Enterprise kit for someone (for money, seriously) and included a fully detailed shutlecraft bay, with glow-in-the-dark paint in the light recesses so it'd have a light source. But the refitted Enterprise largely gutted the secondary hull to triple the size of the space by adding an enormous cargo bay (as shown in the above pictures, probably from ST:TMP. (I have always thought that extended bay was to copy the dramatic view up the landing bay from Battlestar Galactica, but that's just a guess).
Anyway, here's my version. The plans called for painting the walls "off white" a mix of white and light gray, and the storage doors and deck neutral gray (which will be the most commonyl used accent color on the exterior, I can already tell), so I sprayed that and then glosscoated it so the decals would stick. The decals were great, except that the little bit of extra on the storage door decals made them not fit in the recesses. If I'd had some decal set solution it'd have helped them snug down better, but I'll worry about that when they're someplace where they'll show. (I would also have sprayed them with dullcoat after applying if they were where they'd be seen - and will spray to aft end later on, but for the moment I'm just getting used to the idea of applying decals again. It's very possible I haven't done this in about fourteen years).
The ceiling of the bay is extremely detailed, as you can see, and included two large clear plastic lighting sections - clearly this kit was built to be lit from the inside. The whole thing fit together into a solid plastic tunnel, ready to be installed into the secondary hull when it's done.
