A good friend asked me to make some if that damned wrinkly tin. His wife wanted to extend her horse box by 4 feet. It was a real pain as no matter how carefully you mark out each fold and reverse fold any tiny deviation from the 81(IIRC) degree causes a cumulative error and by the time I'd got to the end of the 2.4m the finished piece was about 8mm too long. All the same he was happy with it and bashed it onto the existing section and with a trim strip it looked fine.
Never again!
Never again!
