The kit is hollow-cast, which would facilitate lighting, but I wasn't up to the challenge this time around. I used that internal space to reinforce the model by embedding steel rod through the six arms; resin will sag over time if not properly supported, and with this thing being nearly 20" across when finished, the thin, spindly arms were prime candidates for future drooping.
Painting presented a myriad of choices; most of these "models" that never existed in the real world tend to do that; nothing ever "existed" to replicate the paint from. I went back and forth between silver and gray for several weeks, did some test sprays, etc, and finally decided that since I painted the Cylon Raider in metallics, then it would make sense to follow suit with the Basestar. The overall coat is Tamiya Silver Leaf, over a primer coat of Mr. Surfacer. The Silver Leaf paint only comes in an aerosol rattle can,, which I decanted and shot through my airbrush (I don't trust spray cans for fine finishes). Once that dried, I masked off panels on the outer hull and shot it with Alclad II Magnesium. I then free-handed with the airbrush various details and shades on the hull using the same Magnesium, following the scribed panel lines and hull contours.
The inner parts of the hull were likewise sprayed with Silver Leaf, then shaded free-hand with the magnesium. I brushed Tamiya acrylic Smoke paint -- a dark gray translucent color -- into various recessed areas to increase depth and shading. Once the two hull halves were assembled, the inner parts of the arms looked a little bare, so I made some masking templates and airbrushed several panels here and there, again using the Alclad II Magnesium. A bit of damage on one of the kit arms from a casting defect was given a treatment of burnt metal, black, and some scraping: instant battle damage.
