yup have the same ... take em out, clean it off with a light steel brush, reinstall .... seal it with clear acrylic and clear silicone under the flange if you feel the need ...

come to think of it ... these things are rusting worse than all three neons i owned in the past. soon my 87 wrangler toy truck may have less rust than this thing lol ...

oh well i guess it was not built to last like a Mercedes...
