I guess today they're preping it to be lifted out. The need to make sure that the skid under it that was used to lower it in will still be able to support it. I haven't found any info on whether or not they're planning on unwrapping it there or at the convention center.
Also, remember that the skid under it is made of steel, so there is a chance (however slight) that the rust on top of the car is from that and not the car.
