My 2003 TB has rust along the inside bottom of both rear doors. I've sanded them, primed and painted them and the rust comes through. Does anyone sell replacement sections for these doors?
Maybe if enough of us ask (nicely!), they'll start producing an outer skin?

I'm starting to get it on my rear doors too. No bubbling yet either but its coated in rust on the surface. I've been spraying the body off with a hose nearly every evening after I get home from work. Whatever the state of PA is putting on these highways for ice melter is nasty stuff.
