Progress at last. I cleaned off layers of undercoating and finished contouring the front fender wells. I installed coolant tubing which runs through the central air duct under the passenger compartment. After a few minor details I can paint the front of the chassis from the A-pillars forward. I am using WhiteCote by POR-15. I will start final assembly on the front chassis, suspension, steering, brakes, radiator, etc, as soon as the chassis is painted.
