I have a Seas 5 inch driver that has a ding on its aluminum cone ? see attached image. The ding is an eye sore and I?d like to get it fixed. The aluminum cone is rather fragile to work on and I don?t want to try to fix it without knowing what I?m doing. Does anyone have any ideas of how to safely ?panel beat? the surface to get it to be as smooth as possible? All suggestions will be appreciated.
