How would you fabricate a patch panel for the compound hood corner? I have body hammers and a sand bag. No fancy English Wheels, shrinker or stretchers. Lots of previous damage...about 3/8" of body filler or more. You can see how far it needed to come out when I made the vertical cut. Many dent puller holes already welded up (which shrunk the metal). The portion cut out was swiss cheese and I needed access to fit the rest. TIA.
