The rusty metal is part of the whiskers or felt strip. I used a die grinder and carefully scored it the length of the trim. eventually they broke in two and i was able to pry them out of the stainless steel track. Take your time opening up the track where they're crimped, the stainless track can crack if not careful.
I'll look and see if I took pictures of the process.
I bought my new felt whiskers from
