I don't know what the name of the part is...sorry about that...:doh:
But it's the metal piece on the top where the top meets the body. It makes contact with the rubber seal so I'm not worried about the body rusting. And as far as I know it isn't hurting anything, it's just not that pretty to look at.
I noticed rust on the metal piece. Do I need to take it somewhere to get the rust blasted off and repainted or should I just replace it? If I replace it where can I find the part and what the heck is it called???
