[Nitis]

Looks about like mine. I wire brushed the bad spots then used a rust inhibitor I got at the hardware store then have it a shot of primer. Not much else you can do

Yours looks like mine and I think mine won't get any worse in the meat ten years. And really the only way it can is if it gets to other body panels.

My dilemma is what to use for a floor covering. Since at some point it will be torn up again and hopefully sooner than later
