Burial & Resurrection: Toyota Crown Custom (Part 3)

The body fixation cushion sleeves, which are the most vulnerable parts of the chassis and exposed to corrosion over time, are also made of high-strength stainless steel of A3 and A 5 makes. Stainless steel was also used in producing the short racks of front and back stabilizers. The exhaust system (pipes, resonator as well as the main tank) is also fully made of stainless steel. The bottom and crankcase shields are made of stainless steel sheets. In fact, the bottom is constantly under the aggressive effect of environment and the engine shield is located directly under the radiator. This increases the risk of contact with the cooling fluid, which, in turn, leads to premature corrosion.

One more nuance which increases the durability of the body and the life of the car on the whole. I am talking about the sills, which, sooner or later, under the effect of various factors rot away completely, only if your car is not a De Lorean, of course. Flowing down through all the drainpipes, the whole water collects right in the sills. For drainage, the lower parts of the sills has special openings, which quite often clog up not allowing the water to naturally drain out of the car. This leads to inevitable corrosion. To resolve this issue, (as you’ve already guessed) the sills are also made of stainless steel. The decayed parts from the lower body side were removed and replaced with 100 mm stainless steel pipes, which had already received a series of drainage holes with larger diameters. In addition to the anti-corrosive effect, this modification gave the body additional stiffness.
As for the underbody, at first, it was processed with “Nippon” anti-corrosion primer, after which it was applied with additional prime paint. In the final stage, the bottom was painted in body color and on top of this paint, masters applied the traditional bituminous anti-corrosive layer.
Next time, I will try to tell about the electronic know-how applied in this car.
