Mine had it too, but not too bad. Use Por15 to seal the rust (www.por15.com) - if prepped right, it will stop the rust. Worked for me.

I have read in the archives that 8 of 10 e28s in rustbelt climates have this condition. It is true for me too. I am finally doing some bodywork in this area. So far, I have ground away the flaky paint, undercoating and surface rust revealing an intact structure, but with a 3" perforation into the rocker panel, just wide enough to push a screwdriver blade into it. My plan is to is to repaint with "rust control paint" and then squirt undercoating in the holes. Should I plug them up or should I leave them open for water to drain etc??

Sorry for the mundane question, but winter is approaching again and I need to slow this process down.

TIA,

Jack
