I have a new 2008 525S and have noticed at least 5 approximately 1/8" holes in both sides of the frames. I guess some of them are used to mount nerf bars. I am concerned about moisture getting into the holes and causing corrosion. Does anyone know if the frame has drainage holes? I sprayed some anticorrosion oil into the holes, but I don't want water to build up in the frame. Thank you in adavance for your answers.
