Transported to detail shop yesterday. I went and met with them to go over what needed to be done. They seemed very nice, and interested in helping save the car. It's stored indoors, and behind a locked gate, so it should be in good hands.
The cement under the car, not so good. A lot more carbon and soot than I had hoped. Probably means that despite appearances, the underside of the car has a little soot on it too.
To give you an idea of how thoroughly the smoke leached it's way into small space, those squares with an X shape in them...those were gallons of distilled water for the new radiator. The X is the moulded shape of the bottom of the jug.
The white outline is where a piece of rolled up carpet was sitting under the car. Front of car was to the left, fire to the lower right. It's amazing how the smoke traveled, with more soot up under the front of the car than there is nearer where the fire was. There are cabinets in front of the car that are heavily covered in soot, while items 2 feet from the fire are much cleaner.
