So my car has started to show signs of the dreaded "Honda Rot". Just at the back side of my passenger side 1/4 pannel, I'm starting to get a small buble of rust starting. I pulled my rear bumper off last night to do some investigating and found that the small aporin piece that sits right behind the wheel, where the bumper attaches to/protects the muffler is starting to get pretty soft. It only has what appears to be surface rust so far.

I was wondering if anyone knew if just that small aporin section is replaceable, or am i going to need to invest in a 1/4 pannel?

I'm going to go talk to my body shop on Monday and see what they say, but I want to do some investigation prior to talking to them. I have pics of the rust that I will upload when I get home from work.
