I'm just wrapping the body work on my 51 Ford F1 doors and it occurred to me that I should try to remove the 'waves' in the sheet metal to which the door glass anti-rattler (felt) material glues; not sure how these bends got there and doubt that I did anything to cause these, but they're there now. The section that's wavy won't be visible when the glass is rolled up. My worry is that the anti-rattler once glued will look wavy if I don't do anything to try and straighten it now. On the other hand, if I try to straighten the metal (probably thru some leverage applied from within the door cavity) I might distort the door skin; I would try to spread the levering over as large an area as possible. Any thoughts? Anyone encountered this before? If it's not clear in the pictures, we're looking down into the door where the window glass rolls down. The vent window has been permanently removed.
