Repair vs replace: how a panel shop decides
A damaged panel is repaired if the metal can be brought back to shape without stretching or weakening it, and replaced if it can't — that call comes down to the depth of the damage, whether the crease has stretched the steel, and how close the damage sits to a structural join. Repairing keeps the factory panel and its original corrosion protection; replacing is often faster but means new paint on a bigger area.
