So here are some photos underneath the car. Sprayed in ts-51 and lightly clear coated. The black hand brushed with Vallejo flat black. The exhaust was painted with alclad chrome, base coated with testors enamel gloss black thinned with lacquer thinner. Heat staining was done with Tamiya acrylic clears, yellow, blue, orange. As well as Tamiya acrylic bronze and metallic blue and heat staining powders.
If you look carefully I applied cigarette foil as heat shielding for the transmission
