The dent came out well, I used a piece of hardwood and a dead blow hammer, ( just a heavy, no bounce hammer), and start out EASY!.
Start from one end of your dent to the other, checking your movement after every blow.
It'll come out...........The area may be a little "stretched" afterward, but will pose no problems.
The key is to work slow, and tap it only enough to get some movement.
A baseball bat works well, as your "drift" punch, and a heavy hammer.
Let the hammer do the work, and aim your "drift" well.
