Working on my first project truck F100, will be getting new suspension/drive train. Working with hood and there are ripples and bends in the upper hood including the mid hood peak like it was a little abused. I do know these hoods don't align right (and this one is actually off an ex military F600) so they could see some creative pushing and shoving. I was wondering if there is a way to reinforce the hood so it isn't quite as flimsy. I have the rear cross brace removed currently and was thinking of spot welding a doubler that follows the rear hood line left to right,then double the inside if the hood flange that meets the fender. I was also thinking a piece of half round stock would stiffen the peak detail from ahead of the cross brace position to near the front of the hood. I'm use to working on KC-135s and aluminum more than welding steel,but was wondering if that approach will work without causing more harm than good after I get the wrinkles out or if it's just not needed. Might do a front tilt hinge option is a second reason I would like it less flimsy.
Just to add, the cab edge of the hood had a couple cracks, welded those up but that was also something I wanted to lessen the stress on.

 

In my opinion they are not that flimsy. I have the reverse open hood and all is well. With the braces in it is good to go. If you really wanted you can brace till you run out of rod but I don't think you need to.
