I am trying to finish the rear trim piece on my 29 tudor sedan. It is a 2 piece part and is straight, but needs to bend down around the sides and the slope forward at the same time. I've looked around but have not found them pre-bent anywhere for sale. I've tried to bend it by hand and also tried tacking it down, starting in the middle and working outward, but when I get to that bend the piece wants to distort. Anybody done this before? Success stories? Any advice that I can use to finish this? Thank you for any input. Bob
