<p>Now we're seeing some progress. My earlier effort, just painting over the original builder's work, was not happy. This is much more like what I had in mind.
All the cast aluminum parts are Polly Scale acrylic Flat Aluminum. 
The intercooler air duct and the intake ducts to the turbo compressors, along with the 8 structure tubes leading to the firewall, are a semi-gloss black or near-black. 
</p><p>The rear suspension arms and uprights, pushrod, etc, are satin near-black or very dark gray.
</p><p>The tubing frame from transmission to exhaust pipes, isn't painted yet.
</p><p>Brake discs are carbon, non metallic, so a dark gray. Hubs are a medium gray metallic. Calipers are metallic gray.
</p><p>I mixed up a nice silicone rubber red-orange, applied it over a white undercoat where the intercoolers join the intake plenums, and at both ends of the turbo-to-intercooler aluminum tubes. 
</p><p>Exhaust pipes, waste gates, etc, everything from heads to what passes under the suspension are Polly Scale Stainless Steel. Exhaust turbos need to be dark, oxidized, steel.
</p><p>Shock absorber bodies and remote reservoirs are dark metallic gray, should just be dark gray. Adjustment ring for spring is red over a white undercoat. Springs are yellow over white. Caps / adjustment knobs on top of reservoirs are Testor's Acryl Gold.
</p><p>Air-jack body, between transmission and catch tank, dark gray, with a gold-metallic cap on top.
</p><p>Starter motor is dark gray, incorrect, with a near-black solenoid. Should be near black with a zinc-gold solenoid, black cap at the back of the solenoid, zinc gold bearing housing at the back of the motor.
</p><p>Breather catch tank flat white. Flat aluminum for the tubing pieces that make-up the anti-roll bar adjuster.
</p><p>Drive shafts Testor's acryl metallic gold, with near-black CV housings at each end.
</p><p>High-temp tell-tales on brake discs are white with red and yellow. Not sure carbon discs get tell tails- the hotter the better I think. Iron brakes would have them, for sure.
</p><p>Rear brake air ducts are white undercoat, will get silicone rubber or maybe two-tone brown color coat.
