Spent a couple more hours today with the donut dolly shrinking metal on the roof. The big oil can is now VERY hard to cycle, the depressed area on the forward part of the driver's side is much flatter, and now there are two overlapping (kind of in a figure 8) oil can spots toward the back and straddling the center. The one toward the driver's side rear is basically gone, as it takes a LOT of pressure to depress that area.
Making progress, but it's slow going. Here's another video.
