Been there Done that too! But only once. Get a piece of the edge guard - like on the back lip of the hood - and install it on the sharp edge(s) of the gas flap. In time you will find that there are a lot of places that you can get a pretty bad slice if you aren't careful. The only good thing is that the metal isn't rusty so you don't have to worry quite as much about tetanus.......They make knives out of stainless steel don't they? Keep a supply of Band-Aids handy.
