Masking...

The secondary hull and warp,engines are slightly darker aft of the saucer separation arc. There is an even darker set of panels flanking the aft end of the strongback oval which has been masked off for painting:

Test look with grill...

The medium dark grey I used for the trim on top of the nacelles looks almost the same color as the dark grey primer I used on the photo-etch grills. A good match:

Colors used on this build so far...

The large bottles are...

On the left, the secondary hull, nacelle pylons, nacelles, and ventral saucer light grey enamel;

and the slightly lighter upper saucer and nacelle accent, very light grey.

The small plastic containers (pots) are, from left to right...

Two  pots of the upper nacelle trim (around the blue glowing grill)  medium dark grey, the second pot is just thinned down.

The pot on the right is the color I used for the medium grey panels on the strongback.

There will be more shades to come I'm pretty sure.

Accent colors...

I decided to brush paint the various greys using thinned enamels using Tamiya tape and a liner brush:

A darker grey variant of the secondary and nacelle hull color was used on these panels. I may lighten them a bit once I can see the contrast with the secondary hull lighter grey after de-masking:

Light test after unmasking. I like how the fiber optic "porch" lights turned out:

The lower saucer flood masking tape is removed and cleaned up:

A few spots to clean up in the corners but otherwise this turned out pretty well:
