I had a bit of spare time a while ago and straightened some mouldings (1600 bonnet and light surrounds) that were pretty beat up. I made up some wooden patterns - 5 mins with a saw and rasp, and used a panelbeaters hammer to knock them into shape. Then after getting them as close to OK as possible use a metal file to take out any high spots then sand in stages untill youre at about 600 grit, then steelo pads and a polishing buffer. I was surprised how well they turned out as I was going to throw them away. You definitely won't need to chrome them, just polish will still look good. I'd say try it
