Speaking of the K38, a gallon of the high-build primer was sourced from Auto Body Color & Supply in Tennessee, along with our reducers, hardeners, base colors, and clear for the project. The K38 is a high-build primer that is used to fill in sanding marks and other imperfections and helps even out the body surface. Brian Smith, owner of Auto Body Color & Supply, hooked us up with all we need to finish the fastback, including custom mixed colors for the base and stripes. Auto Body Color & Supply is a full service PPG shop and can mix and ship any of its products. You'll see more PPG product in upcoming issues as we lay out the color and stripes soon.
