Brandon Porter’s AMT 1/25 scale Caterpillar D8H Bulldozer is brought to life with acrylic paints applied through an Iwata airbrush and weathered with a chipped paint effect using the sponge technique. To boost realism, he incorporated pigments, oils, and dirt for gritty, authentic wear. Brandon used brass and lead wire to replicate the engine and hydraulic lines with fine detail. It was a dirty job, and Brandon was just the modeler to get it done.
