I recently came across a great solution to rust-rot forming at the inner lips of hood, doors, and trunk lids -- that little line where the surface metal is bent under and welded.
After thoroughly removing surface scale and cleaning with a good cleaner/solvent, I applied two or three coats of Dow Corning silicone rubber coating. It brushes like a gray colored paint, dries rather quickly, and seals that ugly rusted area from further rot. The silicone rubber is rather expensive $7 plus per quart N but has many other uses around your BMW. so it's well worth the price and available at any good hardware store.

Hi Joseph - I guess there's always possibility of the silcone not sealing completely but Dow Corning silicone does a pretty great job of staying pliable. Depending on the extent of the rust, you could seal it with a stop rust paint (after you've removed as much rust as possible). But for small and/or preventative measures, the silicone is an easy solution.
What if the silicone cracks and allowing poisture to gather and rust develop unnoticed?
