I'd first wash the hood inside and out with a wash and wipe to remove the release agent's from the factory kinda like a bee's wax silicone so the plastic don't stick to the mold... Then sand the hood and before applying the J B weld wash the hood again... Then apply J B Weld.... Good gob 👍 for mine I drilled a small hole at the end of the crack of it would not travel any farther...
Mine broke off at the 2 front mounting bolts do you believe that this process is worth a shot? Have you ever repaired a hood in the mounting area successfully?
