needs heat and something to brace it while it cools
i expect any body whop would pop it in the oven while they bake a car to see if it fixes itself, maybe you could knock up something out of 2x4 which could hold it where it should be in the heating process til it cools and stays
i doubt anyong would take it on as a job, it cant be filled out so just needs manipulating or something behind to push it out to get the deired look, behind would be factory tho
semi flexible steel flat bar fg'd on?
