Jerry,
You didn't believe me when I said we were cousins, did you? LOL!
Well I'll be dog-gone, I have a dent IN MY ROOF TOO!
My Roof Dent Like 64fleetside said
A stud gun and puller would be a better idea.
That's what I plan to use to pull out my dent when the time comes. Another option mentioned to me is to tack weld a washer to the center of the dent (on edge of course) and use a dent puller. The stud gun would be handier and faster though.
