Has anyone had this issue with the stall horn doubler plate (VA-195C): the plate came with a bow in it, presumably from stamping it out vs CNC. After dimpling for the #6 screws and rivets, the doubler was wavy. Tried to correct with gentle coercion with my fluting pliers and got some improvement. After installation, the irregularity was translated to the bottom skin. Not huge but also not smooth. Any thoughts?
