Unlike conventional rotisseries that have the stands on both ends of the car this one supports the vehicle closer to the center. One of the big advantages to that is that it will fit into a shop that isn't any deeper than your car. Doug spent a lot of time trying to center the car weight inside the loops when he made the attaching brackets. The great thing for me is that our Charger should be able to use the same supports that he made for the Coronet.
I've got several different rattle cans of clear here. I haven't ruled out experimenting with them on the aluminum. I've been most tempted to try one of the DUPLI-COLOR Metalcast paints. It's translucent and available in several colors. One of the advantages to trying it would be my ability to try different colors until I decide which I like best.
