It's rust and is typical. The rubber does let some moisture through and after 20 years, the metal strip inside the rubber 'smile' will begin to rust..... probably just chunks of brown oxidized metal remains now. I had the same issue and just replaced the smile. I can honestly say my car is pretty clean and don't know/seen any other rust in/around the vehicle. Don't let this scare you.
