I straightened some stainless for a friend who is building a '61 Vette a few weeks ago. He brought 3 pieces back they damaged installing it. I spent my evening straightening it out .....again.
I have it picked and filed it and have 2 of the three polished. I did it at night at the kitchen table because I am not willing to work on it instead of my own car during the day. It sure is different when the parts you are working on are yours instead of someone else's.
