Hello everyone,

While working on my door of the 337A, I had the door stopped removed and was working on the spring that allows the door to stay open. During that repair, a gust of wind caught the door and pulled it from my hand (I now know to perform airplane repairs in a hanger) and slamed the door into the airframe at the hinge. It cut into the sheet metal and although it is not causing any airworthiness problems, it is irritating to see. Can this sheet metal be repair and how, since it sounds like welding and sanding the aluminum can cause problems.
