Hello everybody! I got my shark fin fitted the other day whilst the chap at the bodyshop was measuring the roof up, he was leaning his elbow on the roof for support. I could see the roof caving in and deforming, when he lifted his elbow after a few seconds the roof came back up again. My heart was crying watching this but I kept quite! I'm just wondering if it is possible the roof can deform/dent/ripple from this kind of pressure/force? Am I being paranoid or was this actually dangerous?
