Re: Damn pricks
If its bent 5cm from its designed point, thats a permanent strain so its been taken past yielding point.
True, there will be an element of strain hardening, although you need to stimulate another permanent strain into it, to return it to its original point (to seal the shut-gap effectively. Without proper heat treatment afterwards and careful working during the operations, its very likely that the stress in the affected area will cause failure of the material....at least thats what I see in it.
If theres a crack in the metal at the bend site then youre knackered Id say.
Replace it. Easier than faffing
Well actually it wouldn't be that weakend, 5cm gap caused by a flexure of something long is a minimal bending. Besides when you bend a metal you gain strength and lose ductility so it is not 'weak'. And more importantly, at that part of the door, it is not like strength is a major issue - its job is only to seal against the rest of the car and enclose the window
