Undentation
The best way to remove any dent is to apply force in exactly the opposite direction that caused the dent. Since I backed the spare into a tree, I'm now pulling on the swingaway strike. I had to climb up and stomp on the buckled lip, but it's back down where it belongs now, and the gap for the glass is even closed up again, like it should be. The t/g skin is just wavier...
