Prepping a "new" Daily Driver truck for me, I had to fix a few dents.
To fix this crease, I made a Vice-Grip slide hammer, and welded a bunch of nails through the dent to persuade it into being.
You can see daylight through here.
Crease is between my finger and thumb. It was ugly.
I welded a wack of nails.
Home-made Vice-Grip dent-puller.
Start around the perimeter of the dent.
Gently persuade them into reason, working yourself into the center.
Grind off the nails.
Might need more than one shot at it. This is "Take II."
Light spray of black paint and a quick sand and you can see the high spots (shiny) and low spots (dark). Repeat as necessary. Or until you can't stand it anymore.
After a big fat roll of Zero-Rust paint.
