Hey all, I have rust on the bottom of the doors of my e32 where the drain plugs for water are. Probably got plugged over the years. Some suggested I get the rusted portion cut off and weld a new piece. But then you run into the problem of the weld being the weak part and trapped air will cause rust. Anyone know of a superior repair shop that can fix this problem. I would like to fix it and be fixed permanently or as close to indefinitely as possible with the help of coatings or rust proofing. Shops don't have to be limited to Chicagoland. I want this fixed. Rust is like a cancer and I can't stand it! Thanks in advance!!
